Pembroke Town Walls

Pembroke Town Walls stand as a Grade II*-listed medieval defence around Pembroke in Pembrokeshire, Wales. Built mostly in limestone rubble, they probably began in the late 13th century under William de Valence, first Earl of Pembroke, after the outer ward of Pembroke Castle was finished about 1280. His son Aymer continued the work between 1296 and 1324, though records from 1377 show the walls were still not complete. A stone wall on the south side was ordered in 1479–80, possibly to repair or finish the existing defences. Only fragments remain of the three original gates, with the West Gate surviving in pieces. Two bastions still stand, one topped by a late 18th-century gazebo. The walls once protected the narrowest point of the peninsula on which Pembroke town sits. They replaced an earlier timber palisade or earthen rampart that guarded the settlement. Money for repairs in 1479–80 suggests the walls were still being strengthened in the 15th century. Much of the original curtain wall has been absorbed into later buildings, leaving only the south section clearly visible. The surviving stretch runs about 225 metres from No. 5 Common Road to Rock Terrace. The best-preserved parts show how the town’s defences tied into the castle’s own walls. Visitors can walk along the remaining south section of the walls and see the two bastions. The gazebo on one bastion offers a quiet spot to look over the town and its surroundings. Fragments of the West Gate mark where one of the three original entrances once stood. The limestone rubble walls blend with more recent structures, showing how the old defences were reused over centuries. The surviving stretch gives a sense of Pembroke’s medieval layout and its role as a defended town.
