Clytha Castle (Welsh: Castell Cleidda) is a folly near Clytha between Llanarth and Raglan in Monmouthshire, south east Wales. Dating from 1790, the castle was built by William Jones, owner of the Clytha Park estate as a memorial to his wife, Elizabeth, who died in 1787. The castle is an example of the Gothic Revival and comprises three towers, of which two are habitable, and linking, castellated curtain walls. Long attributed to John Nash, recent research has confirmed that the architect was John Davenport of Shrewsbury. The folly has views towards the Sugar Loaf and Skirrid mountains on the easternmost edge of the Brecon Beacons National Park. Described by the architectural historian John Newman as one of the two "outstanding examples of late eighteenth century fanciful Gothic in the county", Clytha Castle is a Grade I listed building.

Raglan Castle (Welsh: Castell Rhaglan) is a late medieval castle located just north of the village of Raglan in the county of Monmouthshire in south east Wales. The modern castle dates from between the 15th and early 17th centuries, when the successive ruling families of the Herberts and the Somersets created a luxurious, fortified castle, complete with a large hexagonal keep, known as the Great Tower or the Yellow Tower of Gwent. Surrounded by parkland, water gardens and terraces, the castle was considered by contemporaries to be the equal of any other in England or Wales. During the English Civil War the castle was held on behalf of Charles I but was taken by Parliamentary forces in 1646. In the aftermath, the castle was slighted, or deliberately put beyond military use; after the restoration of Charles II, the Somersets declined to restore the castle. Raglan Castle became first a source of local building materials, then a romantic ruin. It now attracts visitors as a modern tourist attraction.
