To make room for this magnificent quadrangle of his the Cardinal also destroyed the three western bays of the Church of S. Frideswide. He had intended to build a new chapel along the north side of Tom Quad which should rival the chapel of King's College at Cambridge. But this work was interrupted by his fall. The foundations of the chapel have been traced, and they show that the west end ran in a line with the octagonal turrets in S. Aldate's Street, and the walls reached nearly to Fell's passage into Peckwater. For its massive walls Wolsey used some of the stones from the demolished Osney Abbey. The building at the time of his fall had risen some feet above the ground. Dean Fell, it is supposed, used it as a quarry for the construction of his own quadrangle. Now, there had been constructed a new straight walk in the Meadows, and Fell, anxious to improve it, carted the chippings from his own work to lay on it. The chippings were white, so the walk got the name of White. This was corrupted at the end of the eighteenth century to Wide Walk, and hence to Broad [Illustration: Christ's Church] Walk--its present name--which really describes it now better than the original phrase. The destruction of the western bays of the church by Wolsey accounts for the shortened aspect of the nave, slightly relieved though it is by the new western bay which serves as a sort of ante-chapel to the nave and choir which now form the College Chapel of Christ Church. But the appearance of the Cathedral owes something of its strangeness to the fact that it represents, in general plan, the design of King Æthelred's Church reared upon the site of S. Frideswide's. CHAPTER II THE MOUND, THE CASTLE AND SOME CHURCHES The property of S. Frideswide's Nunnery formed one of the chief elements in the formation of the plan of Oxford. The houses of the population which would spring up in connection with it were probably grouped on the slope by the northern enclosure wall of the nunnery, and were themselves bounded on the north by the road which afterwards became the High Street, and on the west by that which was afterwards named Southgate Street, then Fish Street, and is now known as S. Aldate's. This road, giving access from Wessex to Mercia, was probably one of the direct lines from the north-west to London in the tenth century. It led down to the old fords over the shallows which once intersected the meadows of South Hincksey, and gave, as some suppose, its name to the town.[3] The fords were superseded by the old Grand Pont, and Grand Pont in turn by Folly Bridge.
