About Llanthony Priory (Cadw)
Llanthony Priory was one of the earliest houses of Augustinian canons to be founded in Britain, and is one of only a handful in Wales. It is chiefly famous today for its wild and beautiful setting, far up the Vale of Ewyas in the Black Mountains.
It was the priory's remoteness in the Welsh hills which was its undoing, however, making it vulnerable to attack. Giraldus Cambrensis described it, in the late 12th century, as being 'fixed amongst a barbarous people'.
