In the 13th century, the central tower was completed, the Norman apsidal eastern end rebuilt with a Lady chapel and a row of chapels added on each side of the nave, forming double aisles such as are found on many French cathedrals. The spire was completed about 1402 and a free-standing bell tower constructed to the north of the west end.
