the 15th century. The accommodation for the abbots became steadily more luxurious and more private throughout the history of the abbey. Beyond the window are remains of the 12th-century abbot's rooms, which were on a far more modest scale. The large and impressive abbot's hall, with its great west window of six lights, was built in the 14th century, partly over some of the 12th-century abbot's buildings. Below the window doorways led to the service buildings: remains and traces of these mainly 12th-century structures are still visible beyond the western end of the hall. This southern end of the site was considerably modified but preserved after the dissolution, when it was used as a family residence. From the western side of the ruins, the abbot's hall window remains the dominant structure, but walls of the kitchen and dining areas and of the main cloister are easily made out beyond it. It is possible to walk through the entrance to the undercroft of the frater or refectory, below the great west refectory window, which would once have been an impressive structure when it was inserted in the 13th century. The refectory and its undercroft separated the little cloister to the south from the larger northern cloister. The undercroft was the main storage area for provisions, which were brought in through its western entrance from the abbey grounds. A sluice supplied by a stream is on the northern side of the undercroft. The undercroft linked via service steps to the frater above, and by a door to the kitchens, which lay along the western side of the little cloister. The large fireplaces in the west wall of the kitchen range are still very prominent. The frater, being on the upper floor, has gone, but the main cloister wall closest its entrance has two large, arched niches that contained the lavers for the canons' ceremonial ablution before meals. It is not clear how water was supplied to the lavers and all trace of the wash basins has disappeared. The main cloister was a large, almost square, open area, not arcaded like the little cloister, but open to the sky. It gave access to the main theatres of communal life: the refectory, the chapter house, the canons' dorter and the church itself. The chapter house is of exceptional quality and in a good state of preservation. It is fronted by three heavily decorated round
