Honouring individuals with burials and memorials in Westminster Abbey has a long tradition. History Henry III rebuilt Westminster Abbey in honour of the Royal Saint Edward the Confessor, whose relics were placed in a shrine in the sanctuary and now lie in a burial vault beneath the 1268 Cosmati mosaic pavement, in front of the high altar. Henry III himself was interred nearby in a chest tomb with effigial monument. Many of the Plantagenet kings of England, their wives and other relatives, were also buried in the abbey. From the time of Edward the Confessor, until the death of George II in 1760, most kings and queens of England were buried here, although there are exceptions (most notably Edward IV, Henry VIII and Charles I, who are buried in St George's Chapel, Windsor Castle). All monarchs who died after George II were buried in Windsor; most were laid to rest in St George's Chapel, although Queen Victoria and Edward VIII are buried at Frogmore, where the royal family has a private cemetery. Since the Middle Ages, aristocrats were buried inside chapels, while monks and other people associated with the abbey were buried in the cloisters and other areas. One of these was Geoffrey Chaucer, who was employed as master of the King's Works and had apartments in the abbey. Other poets, writers and musicians were buried or memorialised around Chaucer in what became known as the Poets' Corner. These include: W. H. Auden, William Blake, Lord Byron, Charles Dickens, John Dryden, George Eliot, T. S. Eliot, Thomas Gray, Gerard Manley Hopkins, Samuel Johnson, John Keats, Rudyard Kipling, Jenny Lind, John Masefield, John Milton, Laurence Olivier, Alexander Pope, Nicholas Rowe, Percy Bysshe Shelley, Thomas Shadwell, Alfred Tennyson and William Wordsworth. Abbey musicians such as Henry Purcell were also buried in their place of work. Subsequently, it became one of Britain's most significant honours to be buried or commemorated here. The practice of burying national figures in the abbey began under Oliver Cromwell with the burial of Admiral Robert Blake, in 1657. The practice spread to include generals, admirals, politicians, doctors and scientists such as Sir Isaac Newton, buried on 4 April 1727 and Charles Darwin, buried on 19 April 1882. British Prime Ministers buried in the abbey are: William Pitt the Elder, William Pitt the Younger, George Canning, Viscount Palmerston, William Ewart Gladstone, Bonar Law, Neville Chamberlain and Clement Attlee.
