Tretower Castle is situated in the Usk valley threemiles outside Crickhowell. The remains include a motte and bailey castle with a later round tower and a restored courtyard house of 15th century date. The stone castle was built during the Norman conquest of Wales. Today it is the Great tower which dominates the castle site. Together, this substantial fortified manor house and the ruins of Tretower Castle illustrate quite clearly the changing times and fortunes of medieval life. This is an extremely fascinating and evocative site with audio tours available to visitors.
