Wall approximately 4m high and 1.7m thick built of rubble with dressed facing stones, sometimes set in herring-bone fashion, with occasional levelling courses on inner face; 2 rows of putlog holes, lower close to ground level, and upper approximately 1.5m above. Parts of wall, especially to N survive to wall-walk level, with parapet up to 1m high. Towers approximately 5m in diameter. SE tower rebuilt on Roman foundations, and now forms part of Stanley House, as does part of S wall. South gateway of 2 arches follows original plan but rebuilt. Part of S wall incorporated into rear of No 1 Market Square. SW tower largely incorporated into C19 buildings. Parts of W wall built into tower of Church. NW tower exists partly to wall-walk level. Gateway in N wall later insertion with brick-lined arch. NE tower stands approximately 8m high from rock foundations in lower churchyard, and has, to E, bonding stones for former wall flanking quay.
