of the most substantial in Northern Europe. In 741, the church was destroyed in a fire. It was rebuilt as a larger structure containing thirty altars. The church and the entire area then passed through the hands of numerous invaders, and its history is obscure until the 10th century. There were a series of Benedictine archbishops, including Saint Oswald of Worcester, Wulfstan and Ealdred, who travelled to Westminster to crown William the Conqueror in 1066. Ealdred died in 1069 and was buried in the church. The church was damaged in 1069 during William the Conqueror's Harrying of the North, but the first Norman archbishop, Thomas of Bayeux, arriving in 1070, organised repairs. The Danes destroyed the church in 1075, but it was again rebuilt from 1080. Built in the Norman style, it was 364.173 ft (111 m) long and rendered in white and red lines. The new structure was damaged by fire in 1137 but was soon repaired. The choir and crypt were remodelled in 1154, and a new chapel was built, all in the Norman style. The Gothic style in cathedrals had arrived in the mid 12th century. Walter de Gray was made archbishop in 1215 and ordered the construction of a Gothic structure to rival Canterbury; building began in 1220. The north and south transepts were the first new structures; completed in the 1250s, both were built in the Early English Gothic style but had markedly different wall elevations. A substantial central tower was also completed, with a wooden spire. Building continued into the 15th century. The Chapter House was begun in the 1260s and was completed before 1296. The wide nave was constructed from the 1280s on the Norman foundations. The outer roof was completed in the 1330s, but the vaulting was not finished until 1360. Construction then moved on to the eastern arm and chapels, with the last Norman structure, the choir, being demolished in the 1390s. Work here finished around 1405. In 1407 the central tower collapsed; the piers were then reinforced, and a new tower was built from 1420. The western towers were added between 1433 and 1472. The cathedral was declared complete and consecrated in 1472. The English Reformation led to the looting of much of the cathedral's treasures and the loss of much of the church lands. Under Elizabeth I there was a concerted effort to remove all traces of Roman Catholicism
