Beside the cathedral and its monastic buildings, Bishop Roger (1102-39) and his successor Bishop Jocelyn de Bohun (1142-84) built a large Episcopal Palace. It consisted of four ranges around a paved courtyard in the shape of an irregular quadrilateral. The east range was occupied by a large aisled hall with a nave 90-94ft long by 21ft wide, and aisles 11ft to 12ft wide. The piers of the arcades stood on 5ft wide sleeper walls and fragments found during the excavations suggested that the piers were square in plan with spiral shafts at the angles. Excavators believed that the aisles may have been vaulted and the arches of the arcades were moulded with an ornamental hoodmould. Along the north end of the hall were the services including the kitchen. The south range of the palace was set along the north side of the cloister and the west range apparently contained a chamber and a private apartment of the bishop.
Much of the stone of Old Sarum was reused in buildings near the site, in houses in Salisbury and in and around the new cathedral. However, the major collections of carved stones are in the Salisbury and South Wiltshire Museum and the nearby store used by English Heritage. Separate entries have been compiled for these collections.
