'The Roman Town was surrounded by walls, which were approximately along the line formed by the streets afterwards known as Lower Boroughwalls, West-gate Buildings, Sawclose, and Upper Boroughwalls: foundations of the ancient ramparts have been frequently discovered when excavations have been made. They must have enclosed a considerable area, in which the principal buildings stood round about what afterwards became the site of the abbey churchyard. The temple which was speedily erected, and had a beautiful portico of Corinthian columns, stood near the site of the present pump-room. Many fragments were un-carted at the end of the eighteenth century; and the platform on which another temple must have stood was discovered whilst foundations were being dug at the White Hart Hotel in 1867.'
