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.
William de Lacy, a knight in the service of Hugh de Lacy,
is said to have chosen the spot while out hunting,
when he sheltered in a chapel there dedicated to St David.
Very quickly a church was established, dedicated to John the Baptist,
and it was reorganized as a priory in about 1118.
