Pennard Castle was built in the early 12th century, near the modern village of Pennard on the Gower Peninsula in South Wales. Its original timber curtain wall and gatehouse were rebuilt in stone at the turn of the 13th and 14th centuries. Encroaching sand dunes soon afterwards caused the site to be abandoned, and the castle fell into ruin.^[1]

Restoration work was carried out during the 20th century; what remains of the castle was designated a Grade II* listed buildingStructure of particular architectural and/or historic interest deserving of special protection. in 1964.^[1]

History

The Normans began to make incursions into South Wales from the late 1060s, pushing westwards from their bases in recently occupied England.^[2] Their advance was marked by the construction of castles and the creation of regional lordships.^[2][3] Pennard Castle was built after Henry de Beaumont conquered the Gower Peninsula, and made Pennard one of his demesne manors.^[4]

The castle was constructed on a limestone spur, overlooking the mouth of the Pennard Pill stream and Three Cliffs Bay, and was protected to the north and west by surrounding cliffs.^[5]

By 1741 the castle’s south wall had mostly collapsed, but the remainder of the castle was apparently still generally intact. It was a popular subject for engravings, sketches and paintings from the 18th century onwards, with the view of the ruins from the east proving particularly popular. By 1879 large cracks had appeared in the southern tower of the gatehouse, which led to its partial collapse.^[6]

As at 2025 the castle sits in the site purchased in 1920 by the Pennard Golf Club, which is responsible for its maintenance.^[7]
