Cleeve Abbey is a medieval monastery located near the village of Washford, in Somerset, England. It is a Grade I listed building and has been scheduled as an ancient monument. The abbey was founded in the late twelfth century as a house for monks of the austere Cistercian order. Over its 350-year monastic history Cleeve was undistinguished amongst the abbeys of its order, frequently ill-governed and often financially troubled. The sole member of the community to achieve prominence was John Hooper, who became a bishop during the Reformation.
