During excavations at Balkerne Lane in 1973-6 (ECC332), the remains of at least one insubstantial Roman building (CAT Building 35) were discovered fronting onto the south side of the street (MCC475).

The remains of the structure, or structures, consisted of scatters of stake holes and a few small pits together with associated occupation debris on the ground surface.

Occupation debris associated with this and other buildings (MCC483 - MCC486) was characterised by a rapid rate of accumulation and high proportion of sand and charcoal containing much slag and hammer-scale which suggests widespread ironworking in the area. However, the precise nature of this structure could not be established on the basis of the limited excavation of the associated levels.

This building's spatial and functional relationships with MON393 suggest that its use may have taken place after the military abandonment of the fortress.<1>
