Henry III rebuilt the abbey in honour of a royal saint, Edward the Confessor, whose relics were placed in a shrine in the sanctuary. Henry III himself was interred nearby, as were many of the Plantagenet kings of England, their wives and other relatives. Until the death of George II of Great Britain in 1760, most kings and queens were buried in the abbey, some notable exceptions being Henry VI, Edward IV, Henry VIII and Charles I who are buried in St George's Chapel at Windsor Castle. Other exceptions include Richard III, now buried at Leicester Cathedral, and the de facto queen Lady Jane Grey, buried in the chapel of St Peter ad Vincula in the Tower of London. Most monarchs and royals who died after 1760 are buried either in St George's Chapel or at Frogmore to the east of Windsor Castle.[citation needed]
