It is sited on a rocky crag high above a crossing point on the River Wye. The
stone keep was built in the middle of the 12th century, possibly on the site of
an earlier Norman castle. It was strengthened in the early 14th century with a
moat, high walls and 4 strong towers (heagonal inside) using distinctively
coloured local red sandstone. Around the end of the 14th century an outer
defence of walls and a barbican were added. The castle was abandoned by the
start of the 17th century but it was garrisoned during the Civil War. This led
to the outer walls and barbican being slighted but the ruins are picturesque
and well preserved.
