A substantial Roman building outside the south-west gate of the town.

The building was excavated in 1990 at St John Street. Levelled domestic refuse formed a platform for a substantial building. The north wall was located as a 1.9m wide robber trench cut into surviving dump material by about 1m. The robbed foundations clearly had not been bedded on the natural sand. The wall extended into both west and east sections of the excavated area and had a substantial buttress on its north side. The buttress was 1.1m long, 0.8m wide and 80cm deep; it was un-robbed and made of large septaria blocks embedded in mortar. The edge was found of what appeared to have been a robbed out second buttress 5.0m to the west of the first one. No other walls of this building or any associated floor levels were located on this site. The robber trench contained only Roman pottery, the dates of which indicate that the building was demolished in the late 3rd -4th centuries.<1>
