During excavations at Culver Street between 1981-2 & 1984-5 (ECC337), part of a Roman legionary barrack block (CAT Building 81) was excavated. The barracks were situated facing south on the west side of the via principalis (MCC760), north of an E to W street (MCC764) and lay back to back with another barrack block (MCC756).

Most of the internal features of the building had been destroyed by cultivation of the area in the years after the Boudican revolt and the majority of the main plinths had also been robbed during this time. However, within the centurion's quarters at least two internal block walls were found on top of mortared plinths. Other internal walls had single timber-plates which survived as charred fragments.

In the area of the contubernia the central spine wall and east-west plinths to the south were poorly preserved. South of the southern plinth, a few fragments of burnt ground-plate and some possible post pits point to the building having extended beyond the southern plinth perhaps in the form of a veranda with an additional lean-to (see MCC773).<1>
