A Roman drain was seen running obliquely under Rose Lane. This was first found in cellar H and was picked up east of Rose Lane in a trench cut from the surface (K 2). Here the structure was better preserved. In both sections the drain overlay an early ditch which could not be completely explored. It was probably Belgic in origin, of larger size than the ditch found in cellar L (see below); its filling contained Belgic pottery and a few Claudian sherds, implying that it had been closed early in the Claudian period, doubtless as part of the tidying up of the site after the conquest.

Also amongst the discoveries were a pre-Roman Belgic ditch running NE-SW in cellar L with a contemporary occupation to the east .
