Durham Cathedral College forms a close to the south of Durham Cathedral in the city of Durham, England. It is part of the Durham Castle and Cathedral UNESCO World Heritage Site. The college was begun in the late 11th century as an outer courtyard to the monastic foundation established at Durham in 995, and is among the best preserved medieval monasteries in England. On the Dissolution of the Monasteries the college was repurposed to provide accommodation for the dean and 12 canons. Much of the original building fabric remains, although re-fashioning of the exteriors in the 18th and 19th centuries gives the college a Georgian appearance. Many of the buildings have historic listing designations.
