The site of Loughor Castle has a long history. But a single tower that may have once been a keep is the only surviving evidence. Fragments of the curtain wall and further foundations can be found just under the turf. The castle sits at the peak of a hill overlooking the Loughor estuary.

The site of Loughor Castle was once an earthen ringwork castle constructed over the highest point of the Roman fort of Leucarum. It gave protection to a young borough established in the early years of the twelfth century. The Welsh burned the castle in 1151. Around 1220 the land site was given to a Mr. John de Braose who evidently built the present Loughor castle.

Finding Loughor Castle was a real challenge for us. We drove pass the intersection three times. We parked and looked at the bridge that our maps said was by the site. We looked around in despair that there was no sign of a castle. Finally we looked 'up' and to our astonishment the tower was on the hill directly next to where we were parked. We once again had the satisfaction of finding our goal.
