In the centre of what was once a large fortress is an earthen mound with the remains of a thick-walled building on top of it, which may be all that’s left of an earlier keep. Links to Caerphilly Castle too - see plaque in the gatehouse.

Despite the name and its medieval origins, Old Beaupre is really more manor house than castle. Built in two stages, the older part was constructed around 1300 while a major renovation in the 16th century by the Bassett family produced some of its most impressive remaining features. These include the well-preserved three-storeyed gatehouse and striking porch, decorated with columns inspired by the architecture of ancient Greece and bearing the family’s heraldic crest carved in stone

In the beginning, as a castle of earth and wood in the early 12th century, it was quickly fortified in stone before being further strengthened with a curtain wall in the early 13th century. Unusually, the later additions have not obscured the castle’s earliest defensive features, with the banks and ditches built at Ogmore’s birth still clearly visible. Another original feature is the deep ditch around the inner ward, designed to fill with sea water at high tide.
