Penlle'r Castell, Medieval castle ruins in Mawr, Great Britain
The castle remains include earthwork structures with deep v-shaped ditches, a large mound called motte, and remnants of three drystone buildings on top.
Construction of this military frontier castle occurred around 1252 by William de Braose II during conflicts with Welsh lords across the River Amman.
Archaeological studies of Penlle'r Castell reveal the medieval defensive practices and territorial organization methods used by Norman lords in Wales.
Located at 1213 feet above sea level on Mynydd y Gwair summit, the scheduled monument requires careful navigation to access its historical features.
The strategic position of this castle allowed forces to monitor activities of Is Cennan lords and prevent incursions into northern Gower via ridge routes.
