The lower story of Tom Tower was built by Cardinal Wolsey. The cupola was added by Sir Christopher Wren. Three sides of the quadrangle were built by Wolsey, and the north side by Bishop Fell. As we pass through Tom Tower we note that a statue of Cardinal Wolsey faces St. Aldgate’s, and a statue of Queen Anne faces the quadrangle. =Christ Church= is the largest college in the University of Oxford, and stands on the site of the ancient priory of St. Frideswide. In 1524 Cardinal Wolsey obtained authority from Henry VIII. and Clement VIII. to suppress a number of religious houses in various parts of England, and to appropriate their revenues to the building and endowing of a College. After he had made considerable progress in the building of Christ Church he fell into disgrace with the King, who seized the property and distributed it among his courtiers. At a later period Henry VIII. refounded the establishment, and added to it the Abbey of Oseney, which was then the Cathedral of the See of Oxford. Christ Church (the present Cathedral) was at that time called the College of Henry VIII., and was a Collegiate Church. In 1546, on the suppression of Oseney Abbey, St. Frideswide became the Cathedral Church of Oxford. Oseney is depicted in the King window (see page 391). The foundation was converted into one of secular canons in the Eighth or Ninth Century; and these were in turn succeeded by the regular canons, who built their chapter-house, dormitory, refectory and cloisters. In 1158 they began the present Cathedral, which was completed in 1180, having swept away the Saxon church rebuilt by King Ethelred in 1004, according to some critics, while other antiquaries think that much of the present Cathedral is St. Ethelred’s. The church was dedicated to the Holy Trinity, St. Mary, and St. Frideswide, and was somewhat peculiar for the Twelfth Century, in being more elegant than was usual at that time. Cramped for room the south transept was cut off for the sake of the cloisters; and aisles were given to the north transept. There was no room for a Lady-Chapel at the east end; and, consequently, an additional aisle north of the north aisle of the choir was built. The same arrangement occurs at Ripon; the Elder Lady Chapel at Bristol holds a similar position.
