According to the monastic history, Evesham came through the Norman Conquest unusually well, because of a quick approach by Abbot Æthelwig to William the Conqueror. Only one section of walling survives from the actual abbey, although fragments of the chapter house, the bell tower and the gateway remain, which were added later: the chapter house in the 13th century and the bell tower in the 16th century. Simon de Montfort (1208–1265) is buried near the high altar of the ruined abbey, the spot marked by an altar-like memorial monument dedicated by the Archbishop of Canterbury in 1965. The abbey is of Benedictine origin, and became in its heyday one of the wealthiest in the country. During the Dissolution of the Monasteries, the abbey was demolished leaving only the bell tower surviving into the 21st century. Other buildings linked to history of the abbey that survive today are the Almonry and Middle Littleton Tythe Barn.
