The Benedictine abbey of St Mary's was founded by King William II in 1088. The ruins visible today date from a re-build between 1271 and 1294.

Prior to the Dissolution of the Monasteries, it was one of the wealthiest religious establishments in England.

Most of the 'ruins' we see today relate to the abbey's enormous church. Most of the building only survives at, or just above, foundation level. However, the north wall of the nave still stands to window-top height (see Image 2). The lower part of the walls feature decorative 'blind lancets' (dummy window-frames).
