In 1111 A.D., it was granted by either Roger, Bishop of Salisbury, or by Henry I., to Prior Guimond and his fellow canons. This prior began to restore the ruined church and monastery, but his successor, Robert de Cricklade (1141-1180), did most of the work, and restored the nave, choir, central tower and transepts. All the later Norman work is due to him. In 1180, in the presence of Henry II., his nobles and a goodly company of bishops, the relics of St. Frideswide were translated to a place of honour in the restored building on the north side of the choir, to which there was great resort of pilgrims on account of the miraculous healings which took place there. Fire played havoc with the city of Oxford in 1190, but the church escaped without much injury. The monastic buildings suffered, and the traces of fire can still be seen on the old Norman doorway in the cloisters. In the thirteenth century the Lady Chapel was built adjoining the north side of the choir, some of the old walls being used, the spire raised above the tower, the chapter-house and part of the Latin Chapel added, which was completed in the fourteenth century. A few Decorated details were added at this period, and windows in this style inserted. The fifteenth century witnessed sundry alterations in the cloisters, the building of St. Frideswide's latest shrine, the insertion of some Perpendicular windows, and the erection of the fine vaulting of the choir. Then a mighty change dawned on the old monastery. Cardinal Wolsey obtained a bull from Pope Clement VII. for its suppression and determined to convert it into a college, which was designed to be the largest in Oxford. He played sad havoc with the fabric of the church. A great part of the nave he destroyed altogether in order to make room for his great "Tom Quad," so named after the famous bell which still rings each night at five minutes past nine, and is the signal for the closing of the gates of all Oxford colleges. Part of the old cloisters disappeared also. Wolsey contemplated the building of another church for his college, and indeed began its construction; but his fall in 1529 put an end to the carrying out of his great conception, and the college fell into the hands of King Henry VIII. Here the monarch established one of his newly-formed sees (the bishop's seat was first fixed at Oseney Abbey, just outside Oxford), and with characteristic parsimony applied the revenues of the college to the support of the see. The dean of the Cathedral is still the head of the college, and the canons are university professors. As was usual at this time, the Cathedral was shorn of all its costly ornaments, vestments, plate and other treasures, but the fabric remained intact.
