A Gothic Revival folly built as a memorial to a beloved wife, Clytha Castle stands on the edge of the Brecon Beacons with views across Wales’s dramatic mountain landscape.
At a glance
Clytha Castle is a three-towered folly completed in 1790 near the village of Llanarth in Monmouthshire. Two of its towers are habitable; castellated curtain walls link the structures. The castle occupies a Grade I listing and commands views toward the Sugar Loaf and Skirrid mountains.
History
William Jones, owner of the Clytha Park estate, commissioned the castle in 1790 as a memorial to his wife, Elizabeth, who died three years earlier in 1787. For nearly two centuries the building was attributed to the renowned architect John Nash, but recent scholarship has definitively credited John Davenport of Shrewsbury as its designer. The work exemplifies the Gothic Revival taste that animated late eighteenth-century British estates.
What you see
Three towers form the castle’s distinctive composition, with two rising as habitable structures. Castellated curtain walls—crenellated defensive parapets—connect the towers, evoking medieval fortifications. The design harnesses Gothic Revival vocabulary: pointed arches, crenellations, and an asymmetrical silhouette that contrasts with contemporary Palladian restraint. The folly’s siting amplifies its theatrical effect, positioning it to frame views of the mountain ridges beyond.
Cultural significance
Architectural historian John Newman identified Clytha Castle as one of only two outstanding examples of late eighteenth-century fanciful Gothic in Monmouthshire, a county rich in medieval castles and Romantic estates. The building reflects the period’s fascination with picturesque design and the deployment of architecture for personal memory. Its attribution to Davenport, rather than Nash, enriches understanding of provincial Gothic Revival practice in Wales.

Practical information & getting there
Clytha Castle sits near the village of Llanarth in southeastern Wales, roughly between the towns of Raglan and Clytha. The castle’s position on the eastern edge of the Brecon Beacons National Park offers access to mountain walks and scenic drives. Visitors should verify opening times and access arrangements in advance, as the property’s status as a private or semi-accessible folly may restrict casual visiting hours.
