It is a small square tower, built of stone with arched doorways and
tunnel-vaulted. The remains stand to a height of over three metres, abutting up against the later
Medieval City Wall. A descriptive plaque on the Tower stated: :This building is the lower storey of a tower built into a breach in the 4th-century Roman fortress wall perhaps in the reign of King
Edwin (616–632 AD). It was hidden under the
Danish and later ramparts and rediscovered in 1839. A second plaque commemorated the death of archaeologist
Jeffrey Radley in 1970: :This plaque is erected to the memory of Jeffrey Radley M.A. F.S.A. who carried out the excavation of the tower and was tragically killed in a subsequent accident at the site on July 22nd 1970. ==See also==
