The early chapter-house was 26 feet square, and was vaulted with four central pillars. It opened to the cloisters, and the doorway is pronounced to be in the purest style of early pointed architecture.[45] Bishop Lamberton (1298-1328) erected a new chapter-house, and the old one was made a vestibule to the new. South of the early chapter-house was probably the fratery; on the upper floor of this building and the chapter-house was the dormitory--a wheel-stair leading to it from the south transept. On the west side of the cloister was the sub-prior's house, known also as Senzie House; south-east of the fratery is the prior's house or Hospitium Vetus, which was sometimes the residence of the bishop. West of the cathedral are the remains of the entrance gateway, called the "Pends," and in continuation of the "Pends" was the enclosing wall of the priory grounds, containing sixteen towers. The Guest-House was within the precinct of St. Leonard's College, and was built about the middle of the thirteenth century.[46] Within the precincts of the Priory-grounds were the various offices connected with the great ecclesiastical establishment. The conventual and other buildings attached to the Cathedral have been recently excavated at the expense of the late Marquis of Bute, and considerable remains of the foundations disclosed to view. The ruins of the castle stand on a rocky promontory, overhanging the sea, N.N.W. of the Cathedral; and between the Cathedral-wall on the N.E. and the sea are the foundations of a chapel dedicated to the Virgin. In 1559 the Cathedral was attacked by the mob and greatly destroyed. Time and weather helped to complete the work of destruction; the Protestant Archbishop Spottiswoode in 1635 strove to make provision for its restoration, but nothing appears to have been done to arrest the work of destruction. The Barons of Exchequer in 1826 took possession of the ruins, had the rubbish cleared away, and what remained of the great building strengthened. The pier-bases have been made visible, and the outline of the building marked on the turf. St. Andrews has been associated with most of the stirring events in Scottish Church history, and will always possess its two great voices of the Cathedral and the Sea. 2. DIOCESE OF GLASGOW
