Niger died on 29 September 1241[2] or on 2 October 1241[3] and during his burial in Old St Paul's Cathedral, there was an eclipse of the sun. There was a tomb memorial to him in the quire there.[4] His heart was taken to Beeleigh Abbey near Maldon in Essex. Both sites became places of pilgrimage and he was referred to as a saint, although no formal canonisation has been located. He was, however, called a saint by at least one Pope. In 1391, Pope Boniface IX granted relaxation to penitents visiting and giving alms to Beeleigh Abbey on the anniversary of his death.[5]
