Llanthony Priory is located in a valley in southeast Wales, beneath the Black Mountains. It was founded by the knight William de Lacy, who turned to the religious life around the year 1100. Considered one of the finest medieval structures in the region, the monastery had fallen on hard times by the time it and a secondary priory were dissolved in 1538. The artist J.M.W. Turner was later inspired by its ruins and made it a subject of his paintings.
