Fascinating and disturbing visit to the site of the ancient fort system of Caerau

Naming a village after a castle was a mystery until the trees were cut down and the castle was revealed. Its huge moat and high walls make it very impressive - but it the trees are being replanted and it is in danger of being lost again. Ties in with King Arthur, Fortress Glamorgan and the British trackway. Beautiful, scenic and heart-breaking all at once.
