The _West Front_ is entirely modern, the work of Sir G. Scott, but it is designed after the fashion of the ancient front which existed before the hideous construction of the early eighteenth-century architect. As we walk around the Cathedral we must remember that nearly all the work is Transitional Norman, although its character is much disguised by later alterations and the insertion of Decorated windows. The _North Doorway_, with its curious ornamentation, is Transitional Norman, but time and weather have destroyed much of its beauty. The walls of the aisles were raised in the time of Bishop Gower (1328-1347), who inserted Decorated windows. The massive flying buttresses were added about 1500 A.D. On this side was the cloister court of the College of St. Mary, the ruined walls of which appear on the north. This college was founded by John of Gaunt in 1377 for the maintenance of a master and seven priests. The _North Transept_ has been much altered. During the recent restoration the low Perpendicular roof has been removed, and one with a high pitch erected. The north window was inserted by Butterfield in 1846 in place of one which had been blocked up. A curious building is seen on the east side of this transept, which has three storeys, and is higher than the roof of the main building. It contains the Chapel of St. Thomas the Martyr, built mainly by Sir Richard Symonds in 1329, and above it the old chapter-house, and in the highest storey the treasury. The east end of the church was extensively restored by Scott. The Perpendicular roof was retained, but finding amongst the _débris_ the evidence of lancet windows at the east end, Scott reproduced these with excellent effect. The _Lady Chapel_, built by Bishop Martyn (1296-1328), is still in ruins. The south transept has a Transitional Norman west wall, and the rest was built about 1220, after the fall of the tower. Large Perpendicular windows were inserted in the south wall. The old vestry is on the east side. On the south side is the beautiful _Porch_, built by Bishop Gower (1328-1347) in the Decorated style. There is a parvise chamber above. The doorway is remarkable; the sculptures represent the Root of Jesse, with Adam and Eve on the west side and the Patriarch Jesse on the other; above it a representation of the Holy Trinity, with censing angels. The _Tower_ was erected originally by Bishop de Leia, and fell in 1220. It was then rebuilt. Bishop Gower added a second storey in the Decorated style, and above this a Perpendicular storey was raised in Perpendicular times. The wonder is that all this extra weight did not cause the tower to collapse again. It certainly caused continual anxiety, and produced bulges in the neighbouring walls. However, the restoration of Sir G. Scott has secured safety and removed anxiety. The Perpendicular parapet is curious and not very beautiful.
