In 1134, Robert died in Cardiff Castle in his early eighties. Robert Curthose, sometime Duke of Normandy, eldest son of the Conqueror, was buried in the abbey church of St. Peter in Gloucester. The exact place of his burial is difficult to establish – legend states that he requested to be buried before the High Altar. His effigy carved in bog oak, however, lies on a mortuary chest decorated with the attributed arms of the Nine Worthies (missing one – Joshua, and replaced with the arms of Edward the Confessor). The effigy dates from about 100 years after his death and the mortuary chest much later. The church subsequently has become Gloucester Cathedral.
