CARREG CENNEN CASTLE

Although in ruins, Carreg Cennen Castle still boasts numerous passageways and rooms, as well as the remains of towers and ramparts. As much for its historical interest as for its strategic location on a sheer cliff overlooking the surrounding Brecon Beacons park, the castle is well worth a visit. At the far end of the inner courtyard, on the left, don't miss the passageway to the cellars, which will take you deep into the castle, to the passages dug into the rock and said to be haunted.
