Substantial remains of a Norman stone-built castle, raised by the de Londres family. The initial earthwork castle was established by William de Londres, soon after 1100. Idyllically situated beside the river Ewenny, the joining point of two major Welsh counties of Bridgend and the Vale of Glamorgan, the castle was built to guard a strategic fording point.
You can still cross the river via the stepping stones at low tide, but take care as the tide changes quickly and you might get stranded on the wrong side. there is a pathway that leads from the stones to Merthyw Mawr village and sand dunes.
