Recent excavations in Romano-British towns have produced evidence that property-boundaries, once fixed, often persisted over long periods. St. Albans, Cirencester, Leicester, Winchester, and Gloucester have furnished examples, while the results of earlier excavations at Caerwent, Wroxeter and Caistor-by-Norwich can probably be interpreted along similar lines. European parallels may be cited from Augst, Kempten, Xanten and, possibly, Cologne. On those sites where modern excavation has taken place the property-boundaries appear to have been fixed at an early date in the history of their respective towns. It would be of great interest to establish on what basis the original distribution of building-plots was made, especially those sited on street-frontages close to town-centres, where building-land was at a premium and where a systematic allocation of property might be expected.
