Pembroke town walls

Pembroke's town walls are a Grade II*-listed medieval defensive structure around the town of Pembroke, Pembrokeshire, Wales. They were probably built beginning in the late 13th century by the Earls of Pembroke, although it is uncertain when they were finished. Most of the walls have not survived, but there are visible sections and two bastions exist, one with a restored late 18th-century gazebo atop it.
