He was aged only 17 at his death. 1478 – the bones of George, Duke of Clarence (brother of Edward IV and Richard III), and his wife Isabel (daughter of "Warwick, the Kingmaker") are housed behind a glass window in a wall of their inaccessible burial vault behind the high altar 1539 – the cadaver monument which Abbot Wakeman had erected for himself is only a cenotaph because he was not buried there Also buried in the abbey are several members of the Despenser, de Clare and Beauchamp families, all of whom were generous benefactors of the abbey.
