 In May 1366 , as a final sign of royal gratitude , King Edward had Edington elected archbishop of Canterbury . Edington , however , declined on the grounds of failing health . Five months later , on 6 or 7 October 1366 , he died at Bishop 's Waltham . He is buried in Winchester Cathedral , where his effigy can be seen in the chantry chapel he himself had built in the nave .
