It was a very wealthy abbey, and the greater part of the lands in the western, southern, and eastern districts of Fife, as well as in other counties, belonged to it. The abbey also possessed many rights, and the abbot was Superior of lands--the property of others--and received the resignation of his vassals sitting on their bended knees, and testifying all due humility. The abbot and convent were invested with the power of enforcing their rights by excommunication, and they exercised it on several occasions. The abbey possessed the right of a free regality, with civil jurisdiction equivalent to that of a sheriff over the occupiers of the lands belonging to it, and with a criminal jurisdiction equivalent to that of the Crown, wielding the power of life and death. A bailie of regality, appointed by the abbot, and officiating in his name, resided in an edifice called the Bailie House, near the Queen's House, and presided in the regality courts. The abbey church succeeded Iona as a place of royal sepulture, and kings, queens, and princes were buried within it. Gordon gives the list of eight kings, five queens, seven princes, and two princesses, besides other notable persons,[339] so that it may well be called the "Scottish Westminster." The abbey church, when complete, was cruciform, and comprised a seven-bayed nave, with side aisles, a transept, a choir with a lady chapel, and three towers, two western ones terminating the aisles and flanking the gable of the nave, and the great central tower rising from the crossing. The monastic buildings were also on a magnificent scale, but of the church and monastic structures there only now remain the Norman nave, the base of the Lady Chapel, and part of the refectory and kitchen. The nave is well preserved and the piers are circular. The plan of these with that of the wall responds shows that the original intention was to groin the aisles. The two eastern bays between the eastern pillars are built up with solid masonry, and only a portion of the arches is visible. The two western bays and the triforium arches above them have also been filled up with solid building to strengthen the western towers.[340] "The pillars which support the west towers are of greater size than the others, and are of a different section. One of the pillars and the corresponding arch of the north arcade are of late Gothic work, and may be part of the repairs ordered by the Privy Council in 1563, or of the work done in 1594 under the direction of William Schaw, Master of Works, who at that time built the north-west tower and steeple, as well as the porch on the north side of the nave. At the same time, also, certain great buttresses were built against the outer walls, which are now conspicuous features of the structure."[341]
