White Castle is a ruined but super nice castle to visit and sits between the villages of Llantilio Crossenny and Llanvetherine. It is part of the 'Three Castles' group, along with nearby Grosmont and Skenfrith. These historic Norman fortresses were built to control the border region, and White Castle is known as the most imposing due to a strong inner and outer ward. It also has an imposing, water-filled, stone-lined moat. It is free to enter and maintained by Cadw.

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.
