Cresswell Castle was originally a 13th century stone fortified manorial complex, founded by the Augustinian Priory of Haverfordwest. Built to defend the highest navigable point of the River Cresswell, the curtain wall is flanked on the angles by vaulted towers, with the largest being built as a dovecote. In 1553, the Barlows of Slebech converted the fortress into a manor house, with stables, fish-ponds and a garden. Sadly by the 18th century, the site had been abandoned. 3 miles south is Carew Castle and 8 miles north is Llawhaden Castle.
