The castle once belonging to the Umfravilles family. One part of a 13th century stone curtain wall survives along with a semi-circular tower. The first mention of a castle at Penmark dates from 1307, but it seems likely that the castle existed as early as the 12th century. Penmark, Glamorgan, Wales
A wonderfully situated early 12th-century castle overlooking Three Cliffs Bay and Penmaen Burrows, Pennard Castle was probably built by Henry de Beaumont, 1st Earl of Warwick. Beaumont created a ringwork fort surrounded by a bank and ditch, with a stone hall within the earthworks. Of this early fortification only the foundations of the hall are still visible.
St Donat's Castle dates to the 12th century, and has the unusual distinction of remaining in continuous occupation since it was built. Most of the surviving remains date to the 13th century, though there were substantial additions in the 15th and 16th centuries. Remains consist of concentric inner and outer wards, with inner and outer gatehouses. Llantwit Major, Glamorgan, Wales, CF61 1WF

Built in the late 13th/early 14th centuries by the powerful de Braose lords of Gower, William de Braose II and William de Braose III; their descendant, John Mowbray, added to it. In the late 18th century it became, for a while, a debtor's prison. The ruins of the castle are sited in a large plaza, surrounded by modern office towers, providing an intriguing mix of old and new.

Although the towers of Weobley Castle satisfy every requirement of a romantic medieval castle, it is more accurate to describe it as a fortified manor house, with few of the serious defensive features one would expect in a purely military building. Weobley was erected by the powerful de la Bere family in the early 14th century. West Castle Farm, Llanrhidian, Swansea, Gower, Glamorgan, Wales, SA3 1HB
