Dinas Powys Castle
Dinas Powys Castle occupies an isolated, steep sided hilltop on the edge of the modern village of Dinas Powys, commanding wide views toward Cardiff and the coastal plains of south east Wales. The castle stands above a site that had already seen prehistoric, sub Roman and early medieval occupation, making it one of the most archaeologically layered hilltops in Glamorgan. The surviving stone castle consists of the ruined remains of a rectangular courtyard, with sections of curtain walling and the foundation lines of a substantial rectangular tower keep attached to the north western end. This tower, measuring about 18 metres by 13 metres, is believed to be the earliest masonry element on the site, probably dating from the twelfth century. The castle’s courtyard, roughly 68 metres by 32 metres, was enclosed by stone walls up to two metres thick. A broad arched entrance faced the main approach from the south east, and a smaller postern gate with a pointed arch stood in the north east wall, providing a secondary exit. Much of the surviving masonry is now hidden under dense undergrowth, fallen trees and ivy, giving the castle a secretive and overgrown character. The hill itself is steep and naturally defensible. The castle builders enhanced these defences with artificial scarping and terracing, though much of this is now concealed by woodland. The summit has a strong sense of enclosure that reflects its long history as a defended centre. The stone castle was probably established by the de Sumeri (de Sumery) family in the mid twelfth century, shortly after the Norman acquisition of lands in the Dinas Powys area. Roger de Sumeri is thought to have been the first Norman lord associated with the site, using the hilltop as a fortified residence and administrative centre for the newly formed lordship. Excavations in the 1950s revealed that Dinas Powys was already a high status settlement in the sub Roman period (fifth to seventh centuries), with finds including imported pottery from the Mediterranean and high quality metalwork. These discoveries marked it as one of the most important early medieval defended sites in southern Wales. The Normans, recognising its strategic and symbolic value, built directly over this earlier centre. The castle remained occupied for several centuries. Coins from the thirteenth to fifteenth centuries indicate continued use and activity throughout the later medieval period. The decline of the castle likely began with the extinction of the male line of the de Sumeri family in 1322, after which the site gradually lost its administrative importance. By the early sixteenth century, the castle was described as “al in ruine”, and its walls began to collapse into the surrounding woodland. The site has remained ruinous ever since, though its foundations and archaeological richness continue to make it a key location for understanding the Norman and early medieval history of the Vale of Glamorgan.
