Yes / Despite much work on the frontier of Roman Britain, major questions concerned with society and settlement archaeology remain underinvestigated. Salient details of two major urban sites, Carlisle and Corbridge, both of which may shed further light on processes of settlement growth and decline, and which may ultimately contribute to a greater understanding of how the frontier worked, are summarized. At Carlisle, and probably also at Corbridge, settlement growth associated with forts was rapid and multi-tracked, but from the later 2nd century AD changes took place associated, perhaps, with enhanced status and a growing sense of community.
