In 1084, Wulstan, the only Anglo-Saxon bishop to remain at his post after the Norman Conquest of 1066, began rebuilding Worcester Cathedral, starting with the crypt, some of which still survives in its primitive form. Building work continued for nearly three centuries: the two western bays of the nave were rebuilt in 1170. In or around 1202, the central tower collapsed and eventually had to be rebuilt. King John was buried at Worcester in 1216; his tomb is visible in the choir in the view above. In the fourteenth century the central nave was completely rebuilt. The central tower and cloisters were completed by 1374.14 miles)
