Pennard Castle was built in the early 12th century as a timber ringwork following the Norman invasion of Wales. The walls were rebuilt in stone by the Braose family at the turn of the 13th and 14th centuries, including a stone gatehouse. The ruins is a grade II* listed building and a scheduled ancient monument.

 

The castle is reputedly haunted and cursed. Many centuries ago, a powerful chief and his warriors living in the castle attacked a group of fairies outside the walls. The fairies, although unharmed in the assault, cursed the men and the castle to be lost to the elements and lie as a ruin. The castle is also the haunt of the gwrach-y-rhibyn - the Welsh equivilent of the Banshee.
