A ruined former Augustinian priory.
Llanthony Priory is a partly ruined former Augustinian priory in the secluded Vale of Ewyas, a steep-sided once-glaciated valley within the Black Mountains area of the Brecon Beacons National Park in Monmouthshire, south east Wales. It lies seven miles north of Abergavenny on an old road to Hay-on-Wye at Llanthony. The priory ruins lie to the west of the prominent Hatterrall Ridge, a limb of the Black Mountains. The main ruins are under the care of Cadw and entrance is free.

A ruined castle.
The castle dates back to 1087; it was damaged in the 1404 Glyndŵr rebellion and abandoned. Just to be on the safe side, in 1645 Charles I had the remains "slighted" - demolished beyond further use. Later visitors found the ruins picturesque and in 1819 a hunting lodge was built within, in the style of a miniature "keep". This now contains the museum.
One of the best preserved of 3 castles near the Dyke south-east of Llanvetherine. Under 16s must be accompanied by an adult.
