English: St Mary's Priory Church, Abergavenny Pictured here in early morning spring sunshine St Mary's Priory Church in Abergavenny was originally a Benedictine priory founded in the late 11th century by Hamelin de Ballon, Lord of Abergavenny. During the Dissolution of the monasteries the people of Abergavenny gained control of the church. Though dating from the late 11th century what we see today is from the early 14th century.
