The Cistercian Abbey at Tintern was founded in 1131 by Walter de Clare but the remains which can be seen now are of a later date - the church was not completed until the early 14th Century. New cloisters were added in the 15th Century but the abbey was suppressed, along with other monasteries, in 1536. During the slighting of Raglan Castle at the time of the Civil War the records of Tintern Abbey were destroyed, so not a great amount is known about its history. Tintern is located about 21 miles South West of Ross-on-Wye via Monmouth. Other nearby places include Trellech.
