Note 442 — Chapter VII · THE CASTLES OF THE NORMANS IN ENGLAND

The outer ditch may have been of Roman origin, but in that case it must have been carried all round the city, and we are unable to find whether this was the case or not. The banks on the north and east sides must also have been of Roman origin, and if we rightly understand the statements of local antiquaries, the Roman city wall stood upon them, and has actually been found in situ, cased with mediæval rubble. Report of Devon Association, 1895.
