Cilgerran Castle is a 13th-century ruined castle located in Cilgerran, Pembrokeshire, Wales, near Cardigan. The castle is a National Trust property, in the guardianship of Cadw: Welsh Historic Monuments Executive Agency. In 1223 the castle was recaptured by William Marshal the younger, Earl of Pembroke, who rebuilt the castle in its present form. It was later granted by Henry VII to the Vaughan family and they continued to occupy it until the early 17th century, when they built a new house nearby.
