Archaeological monitoring was carried out during the excavation of a sewer trench dug at Firstsite, within the southern part of the former bus station, and on three test-pits dug for a bus shelter in Queen Street. The deeper groundworks reached a layer of late Roman demolition or robbing debris which contained 3rd century pottery. None of the groundworks were deep enough to expose Roman foundations which these remains are thought to seal. Within the sewer trench, this demolition debris was sealed by dark earth (where it had not already been disturbed by the existing sewer trench). In the test-pits for the bus shelter in Queen Street, the Roman levels were sealed by 1m of modern material, with no intervening post-Roman layers. No archaeological features were observed at either site because the groundworks stopped short of the earlier horizons. <1>
