Note 1198 — Chapter XII · STONE CASTLES OF THE NORMAN PERIOD

Conway and Carnarvon consist of two adjoining courts, without any external enclosure but a moat. Flint has a great tower outside the quadrangle, which is sometimes mistakenly called a keep, but its internal arrangements show that it was not so, and it is doubtful whether it was ever roofed over. It was simply a tower to protect the entrance, taking the place of the 13th-century barbican.
