The castle at New Radnor was established in the mid thirteenth century. The surviving remains include an oval embanked enclosure, 50m by 30m, formed from a natural hillock. It is divided by double ditches from a second enclosure to the northwest, 154m by 60m, which is defined by banks and ditches. Both enclosures contain footings of masonry structures and are integrated into the town walls (Nprn303340) of New Radnor (Nprn33219). The castle was ruinous by the early sixteenth century.
