South Wales, on a remote crag about 100 meters above the river Cennen in the Breacon Beacons National Park, was started in 13th century as an English outpost by one of Edward I’s barons. The natural cave beneath the castle rock, perhaps a prehistoric refuge, is incorporated into the defenses via a gallery passage and can still be explored with torches. During the War of the Roses (1455 – 85) it became a base for Lancastrian, who terrorized the country around. The castle was taken by the Yorkists in 1462, this “robbers den” was laboriously dismantled by 500 men with picks and crowbars. The ruins are still very impressive and the views from the hilltop are magnificent. [photo gallery Carreg Cennen Castle]
