Who redesigned Westminster Abbey into its Anglo-French Gothic style in 1245?

Westminster Abbey, formally titled the Collegiate Church of St Peter at Westminster, is a large, mainly Gothic abbey church in the City of Westminster, London, England, just to the west of the Palace of Westminster. It is one of the United Kingdom's most notable religious buildings and the traditional place of coronation and burial site for English and, later, British monarchs.

Since the coronation of William the Conqueror in 1066, all coronations of English and British monarchs have been in Westminster Abbey. There have been at least 16 royal weddings at the abbey since 1100. Two were of reigning monarchs (Henry I and Richard II), although, before 1919, there had been none for some 500 years.

The abbey became the coronation site of Norman kings. None were buried there until Henry III, intensely devoted to the cult of the Confessor, rebuilt the abbey in Anglo-French Gothic style as a shrine to venerate King Edward the Confessor and as a suitably regal setting for Henry's own tomb, under the highest Gothic nave in England. The Confessor's shrine subsequently played a great part in his canonization.
