Small-scale rescue excavations at Llwyn Bryn-dinas hillfort, on the Welsh Borderland, showed that the earliest fortification belonged to the late Bronze Age, with radiocarbon dates in the late 9th and 8th centuries be. A terrace, subsequently cut into the rear of the rampart to accommodate a metal-working floor, was associated with a radiocarbon date centred in the late 3rd century bc. Detailed analysis of the metal-working debris suggests that copper-alloy casting, iron forging and possibly bronze production were carried out within a single workshop. The finds include a distinctive form of handled crucible. The industry appears to have been fairly small-scale, of short duration, and probably only designed to meet the internal needs of the hillfort population. The excavation adds significantly to the local evidence for metal-working during the later prehistoric period. A distinctive zinc-impurity pattern in the copper alloy and raw copper, previously identified in material from other sites nearby, confirms the suggestion of an Iron Age bronze-working industry based on a specific metal source in the north Powys area. In addition, analysis of the iron-working debris suggests the exploitation of a distinctive local ore body. The metal-working activity appears to have come to an abrupt end, possibly with the enlargement or local repair of the rampart. Later phases of activity include a final occupation deposit with an associated radiocarbon date centred in the mid 2nd century bc.

From 1946 to 1952. excavations were undertaken in advance of destruction by gravel workings of a series of Neolithic and Early Bronze Age monuments at Dorchester-on-Thames, Oxon. These included a long enclosure, a cursus, a double ditched henge, pit circles and ring ditches with primary and secondary cremation burials and a notable Beaker burial. Sites I, II, IV, V and VI, all pit circles or ring ditches, were published in 1951. This report describes sites III, VIII, IX, XI, XII, XIII and XIV. By the early 1950s much of the Neolithic complex had been quarried for gravel, and other adjacent areas subsequently were dug away. In 1981 the construction of a bypass led to the excavation of further surviving parts of the complex: site 1, a long D-shaped enclosure incorporated in the southern end of the cursus, and sites 2, 3 and 4.
Both sets of sites are presented together, largely following the chronological scheme proposed for the complex by Bradley and Chambers (1988). Site VIII and site 1 are long enclosures of Earlier Neolithic date, with human remains. The latter site has a calibrated date of 3773–3378 BC. Site III is a cursus at least 1600 m long which cuts site VIII and incorporates site 1. A date of 3360–3040 BC was obtained from the primary fill of its ditch. Site XI is a three-phase ring ditch, perhaps successive enlargements of a barrow, but its innermost ditch is cut by a pit circle with cremations. There are Ebbsfleet sherds in the outermost ditch, and dates of 3037–2788 and 3024–2908 BC from the innermost, perhaps primary, ditch. Site XIV is a ring ditch succeeded by the Big Rings henge. Site 3 is a post circle between the ditches of the southern part of the cursus, with some secondary cremations. It has dates from the outer wood of its posts of 2890–2499, 2886–2491 and 2872–2470 BC; dates on charcoal associated with secondary cremations were 2880–2470, 2870–2460 and 2123–1740 BC. Site 2 is a penannular ring ditch with a primary date of 2912–2705 BC, and secondary cremations. Site XII is a notable Beaker burial within a two-phase ring ditch. An adult man was laid crouched on a bier and was accompanied by a fine W/MR beaker, a stone bracer, a tanged copper knife and a small riveted knife with at least one rivet of tin bronze. Traces of a stretcher-like feature were found in an adjacent pit which cuts the inner ring ditch. Site XIII, the Big Rings, is a large double ditched enclosure with central bank and opposed entrances. There was Beaker pottery in the primary fill of the inner ditch, but very little material was found in either ditch, and there were minimal features in the interior, part of which was stripped. Site 4 consists of two conjoined ring ditches within the southern end of the cursus. It encloses cremation burials. One, accompanied by an awl and Collared Urn, has a date of 2290–1910 BC. Traces of a ditched field system (originally referred to as a droveway, site IX) of later Bronze Age date were found cutting sites III, VIII and XIII, and paired ditches on site 1 may be related.
The complex is related to its local and regional context, and the sequence of development is discussed. A timescale measured in generations is advocated, with phases of continuity and episodes of little activity both represented. Several aspects of monuments are considered: their differing scales including the monumental, their ability to endure and create tradition, and finally the choice of designs, from the locally customary to the exotic.

The excavation of two adjacent round barrows at Trelystan, Long Mountain, Powys, in 1979, has revealed a complex sequence of Late Neolithic and Early Bronze Age funerary structures and traces of Late Neolithic settlement. The earliest structure was a large pit grave, dated to about 2400 bc, which was superseded at about 2200 bc by a settlement represented by stake-walled buildings associated with Grooved Ware. Following this some activity took place, possibly domestic, which is represented by sherds probably derived from several southern Beakers, which by analogy with sites elsewhere are to be dated to a period after about 1850 bc. The subsequent Bronze Age cemetery, dated to between about 1800 and 1500 bc (but possibly continuing later), presents a sequence of burial types and structures which can broadly be seen to illustrate a change from the concept of barrow cemetery to that of cemetery barrow. The earliest burials, which consist of cremations in pits and occasionally accompanied by a Food Vessel, were covered by separate small mounds of stone or turf, or a combination of the two. These were eventually overlain by and amalgamated beneath two larger turf barrows associated with Food Vessel Urns, which employed stake circles in their construction and which acted as repositories for additional cremation burials. The cemetery was sited along a pre-existing boundary fence, set up after the Late Neolithic phase, which was renewed at various times throughout the life of the cemetery in response to changes in its layout. A small undated cemetery of inhumation graves, possibly of the Early Christian period, was founded on the eastern side of the barrows at a later date.
