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 canonisation. The work continued between 1245 and 1517 and was largely finished by the architect Henry Yevele in the reign of Richard II. Henry III also commissioned unique Cosmati pavement in front of the High Altar (the pavement has recently undergone a major cleaning and conservation programme and was re-dedicated by the Dean at a service on 21 May 2010).
