Initially a Norman castle, this great building appears to have been refortified by Henry II in the 1180s, which can be spotted in the very high quality of the masonry. Like many historic buildings in Wales, this castle is looked after by Cadw, the Welsh Assembly Government’s historic environment service. Free to visitors, the monument is set in a picturesque location overlooking the River Ogmore and the town of Bridgend. Established in the early 1100s by Robert FitzHamon, first Norman lord of Glamorgan, it’s visited by quite a few tourists staying in Cardiff — often combining this site with visits to nearby Coity and Ogmore Castles, packing three monuments into one day. For those living in Cardiff these castles are also worth a day trip if you’re interested in Welsh history and monuments, and on a fine day it makes a nice spot for a picnic or taking photos.
