James Berkeley Berkeley died on 24 June 1327, having been murdered and having suffered the destruction and despoilation of his manors, according to the account by his successor John de Grandisson. Berkeley was buried in Exeter Cathedral, against the north wall of the south ambulatory, where survives his chest tomb. It is devoid of the monumental brass which originally adorned the Purbeck marble ledger stone top, in the form of a demi-effigy of a bishop wearing a mitre, the indent of which is still visible. Following the Reformation the brass was stripped away in 1561 on the orders of the Cathedral authorities.
