The present cathedral was started by Abbot Simeon (1082–1094) in 1083. The Anglo-Saxon church was demolished, but some of its relics, such as the remains of its benefactors, were moved to the cathedral. The main transepts were built early on, crossing the nave below a central tower, and are the oldest surviving part of the cathedral. Construction work continued throughout the 12th century. The Western transepts and tower were completed in an exuberant Romanesque style with a rich decoration of intersecting arches and complex mouldings.
