Introduction
Material cultural heritage includes not only spectacular buildings, or works of art under the protection of museums, but also objects related to local industry and crafts. They have a great cognitive potential and are carriers of values defining local identity. However, they are sometimes regarded as less important, depreciated in bottom-up evaluation, because the significance of things/objects depends on human judgement (Hall, Reference Hall1997: 61). Thus the status of individual objects changes depending on the economic, social, and historical context (Ashworth and Graham, Reference Ashworth, Graham, Watson, Barnes and Bunning2018: 375). A negative attitude of the local community to vernacular architecture may result from, for example, a lack of awareness of the value of such objects. They are not taken into account when creating a local brand and their potential is not used in tourism, for example. However, as elements of old heritage, they can become assets of local communities (Ashworth and Kavaratzis, Reference Ashoworth and Kavaratzis2011). Undoubtedly, the group of undervalues objects still includes the ships, rafts and boat mills that have for centuries constituted an important part of the cultural landscape of river valleys (Chętnik, Reference Chętnik1935; Oliver, Reference Oliver2013; Fajer, Reference Fajer2014; Hognogi et al., Reference Hognogi, Marian-Potra, Pop and Mălăescu2021). Unfortunately, few traces of such objects remain today. Single examples of old wooden watercrafts can be found today in Europe mainly in regular and open-air museums.
The local communities that for centuries operated on the major navigable river developed a specific model of coexistence with nature. On the one hand, the river was a threat during floods and ice jams, but on the other, it provided work, both permanent (fishing, ferry crossings) and seasonal (rafting), provided convenient transport and facilitated trade. To transport passengers and goods, many types of river-going vessels were used (McGrail, Reference McGrail2002; Ossowski, Reference Ossowski2010; Reszka, Reference Reszka2012). They differed in size (tonnage) and load type. Apart from typical commercial vessels, some special vessels were designed for single use (Šádova, Reference Šádova1960). The most scant information and data are those relating to floating mills (Gräf, Reference Gräf2006). Only in historical and ethnographic sources can a little information be found for the area of Poland (Szurowa, Reference Szurowa2002; Brykała and Prarat, Reference Brykała and Prarat2018). They have become ‘phantom objects’Footnote 1 of sorts – wiped from the cultural landscape.
Although wooden vessels played an important role in the economy of the state and were significant components of cultural landscape, their material remnants are very rare. Only a few examples of former vessels (mainly smaller ones) have survived to present times.Footnote 2 Most of the identified objects are not entered into the register of immovable monuments and may be completely destroyed in the near future. It happens that we can identify fragments of old boats that have been reused in architecture, in a completely new functional context (for example, see a fragment of a seventeenth-century painting from the Netherlands, Figure 1). So far, reused material from vessels has most frequently been identified in harbour quay structures, floors, pavements, latrines, and much less frequently in traditional vernacular architecture (Marsden, Reference Marsden1994: 11, 153–4; Goodburn and Thomas, Reference Goodburn and Thomas1997; Ford, Reference Ford2013; Pogodziński, Reference Pogodziński2016; Reference Pogodziński2019). They represent a few, but extremely important traces of the old heritage and pragmatic behaviour of local communities, tending to use many times the earlier used items and materials, which resulted from frugality but also respect for possessed things (Strasser, Reference Strasser2013: 517–18). The local/traditional recycling has some characteristics of the idea of sustainability (unknowingly), and preceded or even inspired the current architecture trends (Kiaček, Reference Kiaček2021). This practice is at a border between a phenomenon of symbolic significance – spolia (Kalakoski and Huuhka, Reference Kalakoski and Huuhka2018: 193) – and actions characterised by pragmatism and economic rationalism (Frangipane, Reference Frangipane2016).

This study aimed at compiling an inventory of the last material, non-archaeological traces of wooden vessels, which were dismantled after exploitation, and the material was reused during construction of farm buildings or houses in villages and small towns in the area around the middle section of the Vistula in Mazowsze Płockie (central Poland). We also attempted to identify the type of vessels from which these materials originated and determine if in the architecture of villages and small towns any other material (not wooden) remains of river-going vessels have been preserved.
The Vistula: a cultural and culture-forming space
Mazowsze Płockie is an ethnographic and historical subregion on the northern outskirts of the Vistula’s right bank (Baraniuk, Reference Baraniuk1999: 22; Kasprzyk, Reference Kasprzyk2008: 20–32). The southern border of Mazowsze Płockie is Poland’s largest river, the Vistula (Figure 2), whose proximity was of great importance in the region’s history. Beginning in the fourteenth century, as the role of the Teutonic Order was growing to the north, the Vistula was one of the main trade routes connecting Mazowsze (Mazovia) with the Order. The main goods transported by this river to the State of the Teutonic Order in the Middle Ages included wood, ash and tars. At the turn of the sixteenth century, the importance of grain transport by rafting increased. The growing export of grain transformed cities such as Płock, Zakroczym and Warsaw into important trade centres on the Vistula (Samsonowicz, Reference Samsonowicz1994: 252–9). Until the end of the nineteenth century, the Vistula was Mazowsze’s main transport route. The economic activity of inhabitants of Vistulian villages was connected with the river. Thus, over the centuries, the specific cultural landscape (Enache and Craciun, Reference Enache and Craciun2013: 310) shaped the identity of local communities (Selwyn, Reference Selwyn1995: 119; Guo, Reference Guo2003: 193). Many inhabitants of riverside towns and villages of Mazowsze Płockie were engaged in boatbuilding or worked on vessels navigating the Vistula.

From the sixteenth to the nineteenth centuries, the Vistula was mainly navigated by such vessels as the szkuta, dubas, koza, łyżwa, jadwiga and bat. The szkuta, dubas and koza were flat-bottomed, spindle-shaped vessels with a transom stern and a slender bow, and were equipped with a mast with a square sail and rudders of up to two-fifths of the hull length (Reszka, Reference Reszka2012: 59–60). Additionally, there were raft ships: the byk, galar and komięga, which upon reaching Gdańsk were dismantled and sold as construction material or for fuel (Bogucka, Reference Bogucka1978; Gierszewski, Reference Gierszewski1982: 104; Reszka, Reference Reszka2012: 129–30).
The szkuta was a very popular vessel on the rivers of northern Europe (Ossowski, Reference Ossowski2010: 10). It was the largest vessel on the Vistula from the fifteenth to the eighteenth centuries. It was almost 38 m in length, 9 m wide, and had sides of approximately 1 m high (Smolarek, Reference Smolarek1986). Currently, one wreck of such a vessel exists in Poland, which was discovered in Czersk on the Vistula in 2009 (Ossowski, Reference Ossowski2010: 99–111). Its load capacity is estimated at 87 tonnes. It was in service for sixty years and dates to the sixteenth century. Having been documented, this single complete wreck of the Vistulian vessel was reburied, as no cultural institution had undertaken to extract, conserve and exhibit it.
From the eighteenth century onwards, new types of ships with spritsails began appearing on the Vistula, such as the berlinka-odrzak (‘szpicberlinka’), the berlinka-finówka (‘kafówka’), the kajlak, the krypa and the gabar raft (Reszka, Reference Reszka2012: 59). Vessels of the Szpicberlinka type (German: Oder-Spitzkahn) appeared on the Vistula after the 1773 opening of the Bydgoszcz Canal connecting the Vistula and Oder river systems (Reszka, Reference Reszka2012: 94). This vessel ranged from 30 to 40 metres in length. It was narrower than the szkuta, measuring from 3 to 4 m, which allowed it to navigate canals (Reszka, Reference Reszka2012: 96). The loading capacity of these vessels was from 60 to 100 tonnes. The kafówka differed from the berlinka mainly in its elongated, forward-protruding prow, or kafa (Reszka, Reference Reszka2012: 103). Such vessels were usually built of oak, and sometimes of high-quality pine (Reszka, Reference Reszka1992: 46–7; Ossowski, Reference Ossowski2010: 140–1).Footnote 3
In the latter nineteenth century, kajlaks, which originated from the cyla, appeared on the Vistula. Cylas, known in Prussia as Zille, were built on the upper Vltava River, mainly as single-use ships to Magdeburg, Berlin and Hamburg (Šádova, Reference Šádova1960: 48). The name Zille as a river rafting vessel has a long tradition of use dating back to the fifteenth century (Ossowski, Reference Ossowski2010: 138). The hull was made of 6–7 cm-thick spruce or fir planks. The joints were sealed with moss (Reszka, Reference Reszka2012: 114). Because of the type of wood used, the joints – made of pegs or nails – would not hold, and service life was around three years on average (Ossowski, Reference Ossowski2010: 138). Annually, about four hundred such vessels type sailed the Elbe. After reaching their destination port, most were dismantled (Mielcarek, Reference Mielcarek1986: 28). Only a few, which had a superior, steel-reinforced structure, were converted into freight ships (Reszka, Reference Reszka2012: 114). For this reason, specialised shipyards were created to handle both the dismantling and conversion of these ships (Ossowski, Reference Ossowski2010: 114). The name kajlak endured longest in the Mazowsze Płockie region, and mainly in Wyszogród, where many skippers operated such vessels. They were even referred to as ‘Wyszogród barges’ (barki Wyszogrodzkie) (Ossowski, Reference Ossowski2010: 114–16).
The number of vessels on the Vistula is evidenced by, for example, the numbers in the registers of Gdańsk port, which was the destination port for Vistula rafting and the most important seaport on the Baltic Sea. In 1555, there were 2,100, in 1576 – 2,300, and in 1784 – 2,500 (Gierszewski, Reference Gierszewski1982: 108). By comparison, from 30th March to 30th April 1876 alone, around 101 berlinkas, 14 galars, 1 barge and 172 rafts sailed on the Wyszogród–Płock/Płock–Wyszogród section (Figure 2).Footnote 4
Wooden river vessels began gradually to disappear from the Vistulian landscape in the mid-nineteenth century, when tugs began to be used, and wooden vessels were replaced by steel barges. Despite these changes, berlinkas continued to sail in the vicinity of Płock, Wyszogród and Czerwińsk into the 1950s.
The least studied group of vessels navigating the Vistula is that of floating mills, whose parts could be reused as building materials after disassembly. They were referred to as: młyny okrętowe (ship mills), młyny na promach (mills on ferries), młyny łodne (łodziaste, na łodziach) (boat mills), or more commonly pływaki (from the Polish verb pływać, ‘to swim or travel on water’). In Polish, Vistulian boat mills also had their own name, bździel (Klonowic, Reference Klonowic1862: L. 314). However, in the eighteenth and nineteenth centuries it was used only sporadically.
Floating mills operated mainly on larger navigable rivers, such as the Vistula (Szurowa, Reference Szurowa2002: 98–9; Brykała and Prarat, Reference Brykała and Prarat2018; Brykała and Podgórski, Reference Brykała and Podgórski2020: 6). Such facilities were very common in cities, where they were usually located close to the centre – closest to the potential consumers of their products (Żurawski, Reference Żurawski1970; Rzepkowski, Reference Rzepkowski2015: 239). Certified information about boat mills operating on European rivers dates to the early Middle Ages (Gräf, Reference Gräf2006: 15). Boat mills were mentioned for the territory of Poland in sources from as early as the thirteenth century (using the Latin term super naves). The oldest source mentioning a watermill on the Vistula is considered to be the 1286 charter document of the city of Sandomierz (Dembińska, Reference Dembińska1973: 122–8). They were usually used to grind grain, with one undershot water wheel driving a set of millstones (Rivals, Reference Rivals1993).Footnote 5 They had little energetic capacity, so often functioned side by side in groups numbering in the low double digits (Sabján, Reference Sabján2005).
The oldest mention of a floating mill in the study area dates to 1453. Jan the miller, of a Wyszogród pływak, was mentioned in the records (Wolff and Borkiewicz-Celińska, Reference Wolff and Borkiewicz-Celińska1971: 63). As early as in the sixteenth century, there were eleven floating mills in Wyszogród. A larger group of such mills (Figure 3) also ground grain to meet the needs of the inhabitants of Zakroczym, Czerwińsk and Płock (Gieysztor and Żaboklicka, Reference Gieysztor and Żaboklicka1967: 142; Chlebowski et al., 1900, vol. 15: 374; Żebrowski, Reference Żebrowski2000: 78, 112). In addition, individual mills were located in smaller villages, mainly on the right bank of the Vistula. Until the mid-nineteenth century, such mills continued to be numerous. In Wyszogród itself, fifteen boat mills were still in operation in 1823 (Gawarecki, Reference Gawarecki1823: 22).

The design of the boat mills was similar to that of modern asymmetric catamarans (Figure 4). It consisted of two interconnected boats, a larger one that held the mill and its main grinding equipment, and a smaller one that acted as a float and supported the shaft of the water wheel (Gräf, Reference Gräf2006). Foreigners visiting Poland compared them to such objects in their own countries. Such information can be found in, for example, a report by Fryderyk Schultz concerning his stay in Warsaw in 1791 and 1793. He states that the Warsaw boat mills are ‘similar in structure’ to the mills at a bridge on the Elbe near Magdeburg (Schultz, Reference Schultz1956: 55). Based on analysis of images and preserved technical sections of floating mills, it can be concluded that such objects were fitted on flat-bottomed boats, with which they constituted an integral whole (Szurowa, Reference Szurowa2002: 117). They measured 15–15.3 m in length, 3–7 m in width and 7.5 m in height. The water wheel shaft was up to 12 m long, and the wheel itself was 4 to 6 m in diameter and 6–8 m in length. The water wheel had up to ten blades and made 3.5 turns per minute (Kitzerman, Reference Kitzerman1948: 10; Sabján, Reference Sabján2005: 242).

No. ZKW/438, photo by A. Ring, L. Sandzewicz); (b) boat mill exhibited in the ASTRA open-air museum in Sibiu (Romania) (photo: D. Brykała).
Boat mills were undoubtedly more susceptible to damage than stationary mills. On the rapid wear to the material that boat mills were prone, the lustrator of the Stężyca county wrote in 1789: ‘floating mills are subject to replacement and ruin sooner than terrestrial mills’ (Madurowicz-Urbańska, Reference Madurowicz-Urbańska1965: 270). From the preserved archival materials concerning boat mills on the Vistula River in Płock in 1851, we know that the nine facilities in existence at the time operated for eight to forty-five years (and usually ten to twenty).Footnote 6
However, natural causes were not the main reason for the reduction in number of boat mills. One of the basic factors determining their disappearance from the Vistula and its tributaries was administrative restrictions designed to completely eliminate boat mills. Technical progress in milling ongoing since the mid-nineteenth century should also be mentioned here. Increasingly efficient watermills and, later, steam mills successfully competed with floating mills (Szurowa, Reference Szurowa2002: 126).
The De libertate in fluviis Regiis decree of 1447 (known as the Piotrków statutes of King Kazimierz Jagiellończyk) is considered to mark the beginning of the process of improving the navigability of the river system of Poland, which effectively meant eliminating floating mills (Ohryzko, Reference Ohryzko1859: 69). The document prohibited the creation of obstacles that would hinder transport on navigable rivers, while also allowing dams and weirs to continue operating if they allowed free passage to transport vessels. This regulation mainly concerned named rivers, including the Vistula.
After the collapse of the Polish state at the end of the eighteenth century, the partitioning powers (Prussia, Russia and Austria) initiated intensive efforts to remove boat mills from navigable rivers, and from the Vistula in particular. Decrees were issued specifying new conditions for the construction of mills and their accompanying hydro-engineering structures (permanent weirs and dams). On 30th May 1818, the Royal Governor issued a decree prohibiting the construction of boat mills on navigable rivers.Footnote 7 All mills were to be removed within three months of that date, except for those that received special permission and that did not interfere with the transport of goods down the Vistula.
However, preserved archival documentation shows that boat mills continued to exist on the Vistula for a long time. Although millers were prevented from building new mills, old ones could continue to operate. In April 1871 it was announced that boat mills were to be removed from the Vistula channel within a five-year period (‘Zniesienie młynów na Wiśle’, 1876: 1). On the passing of this deadline in 1876, the Board of District 11 of the Ministry of Communications sent a request to the governor’s offices to issue regulations ‘abolishing all floating mills on the Vistula’ so that in 1877 there were none at all on the river (Gazeta Handlowa 1876, No. 238: 3). It is worth noting that sixty-nine such facilities were in operation on the section from Zakroczym to the border with Prussia at the time (‘Pływaki na Wiśle’, 1876: 2). Such mills were to be officially closed down in the presence of state officials. Did this happen? Evidently not, as another decision (No. 2778) was issued by the Warsaw thoroughfares district (Okręg Dróg Komunikacyjnych) in 1886, ordering that all floating mills on the Vistula were to end operations by the end of 1886.Footnote 8
The final piece of information on floating mills on the studied section of the Vistula River that is confirmed by sources is from the twentieth century. In 1914–15, three boat mills operating on the left bank of the Vistula River near the village of Tokary near Płock were to be liquidated (Dzik, Reference Dzik1928: 9). Surviving even longer, a boat mill operated near Dobrzyń nad Wisłą until the 1930s (Gorzechowska, Reference Gorzechowska1982: 87).
Reuse of boatbuilding materials in architecture along the Vistula river in Mazowsze Płockie
Based on the available data, it can be concluded that boatbuilding wood was being reused in Poland from at least the early Middle Ages until the first half of the twentieth century (Znamierowska-Prüfferowa, Reference Znamierowska-Prüfferowa1988: 137–40; Litwin, Reference Litwin2004; Ossowski, Reference Ossowski2010: 55; Reszka, Reference Reszka2012: 112–13; Misiuk, Reference Misiuk2013: 343; Filipowiak and Stanisławski, Reference Filipowiak and Stanisławski2013: 97, 99 pic. 49, 101 pic. 53). Boatbuilding material was used in the construction of both residential and farm buildings. In addition to this material being used in carpentry, it was also used in new watercraft and as fuel (Litwin, Reference Litwin1995: 44; Ossowski, Reference Ossowski2010: 121, 156, 171; Reszka, Reference Reszka2012: 130; Pogodziński, Reference Pogodziński2016; Reference Pogodziński2019). Similar situations have also been noted in other parts of Europe (Marsden, Reference Marsden1994: 11, 153–4; Goodburn and Thomas, Reference Goodburn and Thomas1997; Ford, Reference Ford2013)
The available data reveals two areas in which such objects occurred. The first is in northern Poland – a strip of the Baltic coast where boatbuilding material obtained from wrecks was used (Filipowiak, Reference Filipowiak2014). The second is the middle-Vistula area, and particularly around Płock, where timber was obtained from river-going crafts.
The oldest structure made of boatbuilding materials in the area of Mazowsze Płockie is considered to be a well casing made of oak planks from the hull casing of a szkuta (Trzeciecki, Reference Trzeciecki2000: 115). It was discovered during archaeological research in the Old Town in Płock, which played an important role in trade on the Vistula.
Identification work in 2017–19 in Mazowsze Płockie, supported by archival inquiries and analysis of published mentions in previous scientific papers, identified a total of twenty objects that had been built using wood from Vistula vessels (Table 1, Figure 2). Unfortunately, most of these constructions have not survived to 2022, including one residential building in Czerwińsk, six residential buildings in Maszewo – the last of which was pulled down in the 1990sFootnote 9 – and one farm building each in Czerwińsk and Murzynowo that were either demolished or burned down. The vast majority of existing buildings are in a very poor technical condition and may be demolished in the near future (Figure 5). Of the entire set, most numerous are residential buildings (14), followed by barns (4), and an item of equipment – a mangle – has also been identified, as well as a well. The largest group of architectural objects built of boatbuilding components that has survived to our times is in CzerwińskFootnote 10 and the vicinity of Wyszogród (including a residential building in Ciućkowo).
Structures built using wooden materials reclaimed from disassembled Vistulian vessels

It is worth noting that, in the late nineteenth and early twentieth centuries, Czerwińsk and Wyszogród played an important role in transport on the Vistula. They had harbours, small ports and shipyards (Ossowski, Reference Ossowski2010: 145), and the life of their inhabitants was inextricably tied to the Vistula. River-going craft were also dismantled in these places. The last certified cases of the disassembly and sale of boatbuilding material date to 1954 and 1955 (Reszka, Reference Reszka2012: 112). An eyewitness to the demolition emphasised that the wood was healthy, and the best preserved were brety, that is, oaken planks of the hull casing (Reszka, Reference Reszka2012: 112).
There is also information about the reuse of material obtained from boat mills. The best example is a barn in Murzynowo near Płock that was built of material from a disassembled floating mill (Olędzki, Reference Olędzki2016: 79, 311). Photographs of the building have survived. The boards used in the construction have numerous characteristic holes for the pegs that fixed the floating mill’s component parts. Information about the origin of the material was passed down from generation to generation in the family. Its veracity is attested by Jacek Olędzki – an ethnographer who has conducted research in Murzynowo for many years. Another example of material from a floating mill being reused was a building in Błotnowola in the upper reaches of the Vistula River. Due to administrative restrictions preventing the free operation of the boat mill, its owner decided to end the life of the pływak. In 1820, he used the obtained wood to build another type of grain mill – a windmill (Szurowa, Reference Szurowa2002: 105, fn. 39). There have also been instances of floating mills being adapted to entirely new functions. This was the case, for example, in the village of Nakieł nad Bugiem. Before 1820, two floating mills were retired, and an inn was established in one of them (Chlebowski et al., 1885, vol. 6: 884).
In summary, the architecture of Mazowsze Płockie was for centuries dominated by wooden buildings. However, deforestation and its resulting problems forced residents to seek alternative sources of traditional building material or to use other materials (Fischer, 1934: 166–7; Czerwiński, Reference Czerwiński1995: 60). Early twentieth-century data confirm the paucity of forest cover in the Płock county (Kozicki, Reference Kozicki1905: 265). Despite insufficient forest resources, wooden architecture predominated in what was then the Warsaw voivodeship (Ciołek, Reference Ciołek1952: 245–6). According to the findings of M. Kacprzak, after the First World War, the most numerous group of buildings in rural Płock were wooden structures (59.5 per cent), which was in line with the nationwide trends in rural construction at the turn of the twentieth century (Kacprzak, Reference Kacprzak1937: 58–9; Ciołek, Reference Ciołek1984: 110). This predilection may have resulted from both the peasantry’s conservative attitudes towards construction, or an innate aversion to change (Ciołek, Reference Ciołek1984: 119). In light of the difficulty in obtaining suitable carpentry material, the use of boatbuilding wood in Mazowsze Płockie’s rural and small-town construction should be considered one of the remedies to the situation. It is also a perfect example of unconsciously environment-friendly activity, consisting in recycling of still useful and highly valuable boatbuilding material for building construction.
The barn from Rębowo at the Museum of the Mazovian Countryside in Sierpc as an example of an ‘architectural palimpsest’
In the Museum of the Mazovian Countryside in Sierpc (Muzeum Wsi Mazowieckiej w Sierpcu) there is a unique item of wooden architecture – a barn from Rębowo, a village less than 3 km from Wyszogród. Boatbuilding wood from a dismantled Vistulian craft was used in its construction (Figure 6). According to archival information,Footnote 11 the wood comes from a berlinka dismantled in Wyszogród.
Barn from Rębowo exhibited in the open-air museum in Sierpc. (a) general view with southern wall marked; (b) arrangement of boatbuilding peg holes in southern wall; (c) example of surviving boatbuilding peg, with wedge inserted (photo: R. Piotrowski).
The barn was built in 1895 from pine wood. It belonged to the Woje family. The object, on a rectangular plan of 19.60 m by 7.60 m. The sole plate was laid on a foundation of fieldstones. The posts were made of oak and pine wood. The interior of the building consists of a large haymow, a ride-through main hall and a separate granary. One element of a roof truss has the inscription ‘F Józef i Bregida IHS Woje Roka 1895’. The foundation inscription refers to the date of the barn’s construction and the name of its owners, while the monogram IHS is a symbol of Jesus Christ.
At the beginning of the 1980s, the barn was purchased by the open-air museum in Sierpc as a typical example of this type of building in the Mazowsze Płockie region. The barn was reconstructed as part of a homestead in the museum village. Structural elements of the barn have certain features that are convincing of the authenticity of the information displayed alongside the exhibit. These include dowel holes, and the shape of the dowels themselves, which have a circular cross-section and are wedged in with elongated pyramidical oak wedges. This is a typical solution in river boatbuilding (Ossowski, Reference Ossowski2010: 101). Most of the components with dowel holes are found in the building’s southern wall, in which no planks were replaced during reconstruction apart from the sole plate. In the western wall, the sole plate and three log beams were replaced, and seven log beams in the northern wall.Footnote 12 Based on information in archival documents, after analysis of the building’s individual structural elements, and based on field data confirming the frequent use of recovered boatbuilding material in Mazowsze Płockie, it was hypothesised that the building material originated from a dismantled berlinka (Piasecki et al., Reference Piasecki, Piotrowski and Pogodziński2017). This hypothesis is evidenced and probable. However, some of the construction details that can be recreated from the elements preserved in the barn walls do not have characteristic features of construction material from berlinkas. In the known flat-bottomed vessels, the hull-bottom planks were fixed with pairs of pegs. The holes for the pegs were offset against each other by about 45 degrees (Figure 6b). In the planks of the front wall of the barn from Rębowo, a series of peg holes at two heights was identified. The distances between successive holes range from 71 cm to 76 cm. In the gable and rear wall of the building there are planks with pairs of holes arranged ‘one on top of another’ or in series, and perpendicular to the longitudinal edges of the boards. The vertically placed holes are 24 cm apart. Meanwhile, the distances between pairs of holes (longitudinal distances) range from 188 cm to 224 cm. Planks of the gable wall have also been identified that feature other combinations of holes that form, for example, an isosceles triangle. The distances between the holes are 12, 12 and 14 cm (Figure 6b). Another feature that does not fit the design solutions used in berlinkas is the diameter of the pegs. Most of the holes have a diameter of 2.5 cm to 3 cm (Figure 6c). Vessels on the Vistula usually had pegs with a diameter of 3 cm to 3.7 cm. Also, the thickness of the planks is not indicative of the hull casing’s bottom planks (even taking into account shrinkage of the wood). In most cases, these boards are approximately 4 cm thick. Only one of them has a thickness of 7 cm. These types of dimensions are found in smaller vessels, such as bats. The hull-bottom planks used in bats were up to 5 cm thick, while the sides were approximately 4 cm thick (Reszka, Reference Reszka2012: 78). The width of the planks is also too small to be interpreted as berlinka hull-bottom planking.
At this point, it should be asked whether there are any indications that the material used to build the barn can be identified as parts of a floating mill. It is likely, given the design of these mills. First of all, some boards have a series of single peg holes: these are unlike berlinkas, in which peg holes appeared in pairs, often angled at 45 degrees to each other. This material can be considered to derive from the asymmetric, smaller float on which the mill wheel shaft rested. The density of pinning would indicate joining to the frames of a flat-bottomed vessel. Importantly, taking into account the graphical materials relating to boat mills – the smaller boat of a boat mill is structurally reminiscent of a ‘simpler’ river vessel – the aforementioned bat (Miholek, Reference Miholek2013: 131–2). This would explain the dimensions of the boards and the distribution of peg holes. There is also a good chance that the material used to build the barn from Rębowo is from the side planks of a boat mill (Kulich, Reference Kulich2002: 13; Gräf, Reference Gräf2006: 88, 143, 188). These boards may also come from the mill house itself of the floating mill. Taking into account the framing construction of the ‘superstructure’, this is likely. The more so because the distances between frame posts in sections of mill walls often ranged between 0.7 m and 1.2 m (Streza, Reference Streza2014: plate I. 13.2).
An interesting research thread in the context of our considerations is a rosette identified on one of the barn planks (Figure 7). It is 24 cm across, with an isosceles cross inscribed in its circle. For such objects as, for example, berlinkas, no woodworking ornaments have been found, and no pertinent information has survived. Similar decorations, including hexapental rosettes, have been found on vessels of older provenance, for example, szkutas (Ossowski, Reference Ossowski2010: 112–14). Taking into account the specific status of the mills, it can be assumed that apotropaic signs were popular on floating mills. Decorations identified in the interiors of watermills and windmills, including the presence of hexapental rosettes (stars), are per analogiam evidence supporting this hypothesis (Wesołowska, Reference Wesołowska1969: Fig. 6; Adamczewski, Reference Adamczewski2001: 99–100). Further confirmation may be the rich woodcarving of the interior of the watermill shown by Daniela Gräf (Reference Gräf2006: 192, Fig. 328). However, the rosette found on the plank from the Rębowo barn is not a hexapental star but an isosceles cross inscribed in a circle. Is it a carpenter’s mark, an apotropeion in the form of a cross, an ideogram of a four-leaf clover (Wyrwa, Reference Wyrwa2018: 41), or, in the end, an ideogram of a water wheel (Irimie and Bucur, Reference Irimie and Bucur1969: 429–31)? These questions cannot be answered unequivocally. However, it should be remembered that mills had a specific symbolic status that generated many beliefs. Boat mills probably did not differ from stationary mills in this respect (Kulich, Reference Kulich2002: 101, 116–17). Thus, this rosette need not have fulfilled a purely aesthetic function, but may also have been symbolic, and perhaps apotropaic.

Taking into account the year the barn was built (1895) and the information contained in the building’s inventory card concerning the material’s provenance from a dismantled berlinka, it can be assumed that the family of owners (heirs) preserved the information about the alleged source of the building material. However, due to the time lapse between the construction of the barn and its purchase by the Museum of the Mazovian Countryside in Sierpc (over eighty years), as well as the distance from the Vistula River and the lack of direct contact with the traditions of inhabitants of riverside settlements, the account of the ‘informant’ (who was not a witness to the purchase) may be erroneous in its identification of the building. As a consequence, the name of the object was changed. The boat mill (młyn łodny), often referred to as a floating mill (pływak), could be ‘transformed’ in family accounts into a river-going vessel, especially since in Polish the młyn-pływak (floating mill) derives from the verb pływać that indicates sailing or swimming (a berlinka also sails). Information on the material having come from a berlinka may be the result of the common occurrence of these vessels, and from their use in the 1950s on the Vistula near Czerwińsk and Wyszogród. Therefore, the idea that this material comes from boat mills operating in Wyszogród should not be unequivocally rejected. The reuse of material from such objects is confirmed by the aforementioned examples from Murzynowo near Płock and Błotnowola.
The phenomenon of reusing material in vernacular architecture was quite common in the past.Footnote 13 However, in this case we are dealing with an unprecedented phenomenon, when vessels were the source of reused material. Thus, the function of a new structure was radically different from the function of the structure from which the material was obtained (Kalakoski and Huuhka, Reference Kalakoski and Huuhka2018: 193).
Millstones in the space of villages and towns along the Vistula
Pieces of evidence suggesting the possibility of wood origin from boat mills can be supported by other material elements identified in the architecture of villages and towns along the Vistula. This applies also to millstones. Unfortunately those used in floating mills did not differ remarkably from the millstones used in other mill types (windmills, watermills). That is why it is difficult to attribute them to this mill type unambiguously without the context of other archaeological findings (see e.g., Dumont, Reference Dumont2015; Joziasse et al., Reference Joziasse, de Ruiter and Pouwels2019). However, considering that boat mills were for centuries the most numerously represented mill type in villages and towns along the Vistula, this is highly probable.
In the study area we surveyed eleven localities where millstones were identified. Most of them are embedded in church walls (seven cases) and one in a residential building (Figures 8 a,b). Fragments of millstones were also found in a pavement of a driveway to a property in Wyszogród (Figure 8d), in a pavement near the main entrance to the church in Czerwińsk, and two millstones were exposed near a roadside cross in Czerwińsk (Figure 8c). A similar phenomenon of reuse and exposure of millstones from windmills and watermills, near the places where they were operated in the past, is known from many examples (Święch, Reference Święch2005: 148; Piotrowski, Reference Piotrowski2021: 90–2; Piotrowski, Reference Piotrowski2022: 26–7). The millstones identified in the study area are semi-finished or damaged, with traces of use (either whole or fragmented).

Brykała and R. Piotrowski).
Most intriguing are the millstones exposed in the outer walls of Christian temples. Most of them are found in walls of Gothic churches (six cases). In the study area, they are buildings dating back from the fifteenth and sixteenth centuries, that is, from the period when in this section of the Vistula valley the first boat mills appeared, which is confirmed by historical sources. Even more interestingly, the cases of incorporating of millstones in the walls of churches in Mazowsze Płockie are found nearly exclusively in towns and villages located in the vicinity of large navigable rivers. In other regions, also similar examples of churches with embedded quern-stones or millstones are recorded (Herzberg, Reference Herzberg1994: 24–33; Jędryka, Reference Jędryka1994), but without such an association of their location with hydrography. Some authors indicated a possibility of a symbolic meaning of such artifacts in a sacral space (Peacock, Reference Peacock2013: 169–72; Watts, Reference Watts2014: 40–2; Brykała and Lamparski, Reference Brykała and Lamparski2021).
Conclusions
The use of boatbuilding material in rural and small-town architecture in Mazowsze Płockie should be considered a specific and significant element of the region’s cultural heritage. It resulted from both the high-quality wood used to build river ships and, mostly, to the local shortage of wood material in the nineteenth century. Importantly, the rationality and pragmatism of the inhabitants of Mazowsze Płockie produced an unconsciously ecological activity. The use of reclaimed material that is at hand (timber from building demolitions, but also materials such as clay or stone) is a kind of rural architectural bricolage (Piotrowski, Reference Piotrowski2020). We should also bear in mind the question of sentimental and emotional value, which is difficult to verify. The interviewees from Czerwińsk emphasised that building a house made of boatbuilding components was an affirmation of the professional affiliation of their ancestors and their relationship with the Vistula, as well as being emblematic of local Vistulian identity. Objects of this type, when promoted appropriately, could become tourist attractions, strengthening the local brand and positively shaping the social and cultural identity of places (Ashworth, Reference Ashworth1994). This confirms the thesis about the importance of spolia as bridges connecting the past with the present (Kalakoski and Huuhka, Reference Kalakoski and Huuhka2018: 209).
The barn from Rębowo at the Museum of the Mazovian Countryside in Sierpc should be considered the only object under the protection of a museum in the Mazovian voivodeship to represent the reuse of boatbuilding material – probably from a boat mill – in the rural architecture of Mazowsze Płockie. It constitutes an ‘architectural palimpsest’ of sorts – a building with a ‘double identity’ responsible for preserving the material of now-defunct Vistulian vessels that were for centuries associated with Mazowsze Płockie. This happened by chance. The barn is under museum protection not because of the origin of the material, but because its construction is typical for the region. Thus, thanks to a combination of events, this barn bore a memory of a no-longer-extant or dematerialised item of the region’s cultural heritage. Thus the value of this object does not derive from their aesthetic or structural values, but mnemonic ones – referring to the culture of earlier human communities that inhabited the Vistula valley and its vicinity (Ashworth and Poria, Reference Ashworth and Poria2009: 523).
In European open-air museums, we still see several preserved or reconstructed boat mills (Ruşdea, Reference Ruşdea1986; Jüngel, Reference Jüngel1987: 96; Juhász and Krivošová, Reference Juhász and Krivošová1996: 16). Unfortunately, no open-air museums in Poland have managed to preserve objects of this type. It has only been attempted to reconstruct such an object. In 2013, a copy of a boat mill was exhibited at the Museum of the Kielce Countryside in Tokarnia. Unfortunately, the project came to an end after four years (Mosakowski et al., Reference Mosakowski, Brykała, Prarat, Jagiełło, Podgórski and Lamparski2020: 54). Another example is the idea of reconstructing a Vistula floating mill in the ethnographic park in the Kampinoski National Park in Granica, on a specially widened section of the Olszowiec Canal (Szałygin, Reference Szałygin2005: 382).
Considering the above, the barn from Rębowo has an important, but not fully realised, value. It is our material heritage, not only of vernacular architecture in Mazowsze Płockie, but also of traditional boatbuilding in the Vistula valley. The barn structure is very likely to preserve some elements of a boat mill. Thus in the open-air Museum of the Mazovian Countryside in Sierpc, an exceptional object of remarkable cognitive value is located. It can be classified as a unique example of architectonic recycling and a specific instance of the idea of sustainability, resulting from local pragmatism and economic realism.
