This part of the Upper Thames Valley is rapidly becoming one of the best-mapped areas of Roman Britain. Excavations at two quarry sites in Gloucestershire revealed a dynamic pattern of land-use and settlement extending from the middle Iron Age through the entire Roman period and into the early post-Roman era. In the middle Iron Age, the site was clearly a settlement area with two broadly contemporary clusters of round houses, metalworking activity and associated fields.The Roman evidence consisted mainly of ditched land divisions spanning the entire four centuries, and although there was no direct evidence for any settlement, there must have been one nearby. The remarkable density of features in this landscape shows an almost obsessive emphasis on the redefinition of boundaries, which contrasts with other recent large scale investigations in the area where a much more open landscape has often been revealed.
