His body was buried at Fontevraud Abbey near Saumur in France, as are his father and mother. His internal organs were buried at Chalus, near Limoges in central France. His heart was buried in the Notre Dame Cathedral at Rouen. It was found in 1838 and was examined by scientists in 2012.

There is no evidence to support this idea, and he probably died from gangrene or septicaemia from the arrow wound.
