St-Calais died on 2 January 1096 after falling gravely ill on the previous Christmas Day. Before his death he was consoled by Anselm and was blessed by his former opponent. He was buried on 16 January 1096 in the chapter house at Durham. The king had summoned St-Calais shortly before Christmas to answer an unknown charge, and it is possible that the stress of this threat caused his death. In 1796 St-Calais' grave was supposedly found during the demolition of the chapter house at Durham Cathedral. Found in the grave were a pair of sandals, which still survive, and fragments of a gold embroidered robe.
