Llanthony Priory

Top choice in Brecon Beacons National Park

Halfway along the impossibly beautiful Vale of Ewyas lie the atmospheric ruins of this Augustinian priory, set among pasture and wooded hills by the River Honddu. Perhaps the second most important abbey in Wales when completed in 1230, it was abandoned after Henry VIII dissolved Britain's monasteries in 1538. Running a close second to Tintern for grandeur, Llanthony's setting is even more stunning, and you won't have crowds to fight. JMW Turner was impressed, too: he painted the scene in 1794.
