The public entrance to the abbey site is now on the south side, where the extant ruins are at their most impressive. Visitors are confronted by the elaborately decorated, five-sided bay window of the abbot's private quarters. This is of very late date – probably the second half of 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.
