Chepstow Port Wall

The wall originally formed a semi-circle extending for some 1,100 metres (3,600 ft), roughly southwards from Chepstow Castle to the River Wye.

Because of its status as a Marcher lordship, dues were levied by the local lord, outside any direct control by the English crown.

He was also responsible for the building of the Port Wall, usually dated at 1274–78, and the Town Gate; and, in 1294, for granting to his close associate, John ap Adam of Sedbury, the right to hold a regular market at Chepstow.

It was built without any substantial foundations, and is faced with roughly squared blocks of stone ashlar and filled with rubble.

Gaps in the wall were later opened to give vehicle access to the main town car park at Welsh Street in the 1960s, and for a new relief road (A48) in the early 1970s.
