A Roman building discovered during excavations in the grounds of St Mary's Rectory in 1967 (ECC661). The remains consisted of a mortar dwarf wall running east-west and an associated clay floor on its northern side. The wall was aligned differently to an adjacent excavated building (MCC1607). The building had been burnt down in the fires of the Boudican revolt and was covered in a thick layer of burnt daub which survived fresh and unweathered and sealed by the lowest surface of a north - south street (MCC1642). The building was also covered by the later towns defensive rampart and wall.<1> Crummy suggests that the building could have been military in origin that fronted the eastern side of the fortresses intervallum road. Its construction suggests that it was a barrack building.<2>
