The ruins of Hailes Abbey are a National Trust Property in Gloucestershire, a few minutes drive from the headquarters of the Gloucestershire Warwickshire Railway in Toddington. A Cistercian Abbey, it was completed around 1250, but was a victim (like nearby Evesham Abbey) of the Dissolution of the Monasteries and was shut down in 1539. Demolition occurred over the next couple of centuries, leaving the ruins seen today. Although owned by the National Trust, the site is managed by English Heritage.
I have made three visits to Hailes Abbey, with most of the photographs in this collection being from the second visit.
