(Royal Tombs of Medieval England) The younger brother of Henry III, Richard of Cornwall died at Berkhamsted in April 1271 and was buried at Hailes Abbey which is northeast of Winchcombe in Gloucestershire. His heart was buried beside his third wife Beatrice before the high altar in the Franciscan church, Oxford, beneath a 'sumptuous pyramid of wonderful workmanship.'
Additional notes about Hailes Abbey. (Royal Tombs of Medieval England) Hailes was a Cistercian house which Richard founded in 1246 as a cell to his father King John's foundation at Beaulieu Abbey. Hailes had its own relic of the Holy Blood, presented in 1270 by Richard's son, Edmund, who was also buried there together with Richard's second wife, Sanchia of Provence (d.1261), and other sons, Henry of Almayne (d.1271) and Sir Richard de Cornwall (d.1296). Henry, murdered at Viterbo, had a separate heart burial in the Confessor's Chapel at Westminster. In the late 13th century Hailes was the most senior of a series of aristocratic mausolea. There are no records of the Hailes tombs, which were probably destroyed following the surrender of the abbey to the crown in 1539. Excavations at Hailes in 1900 did find some stone effigy fragments in the south presbytery aisle bearing the arms of Cornwall.
Heart burials. (Royal Tombs of Medieval England) Richard of Cornwall's first wife, Isabella Marshal (d.1240), was buried at Beaulieu Abbey and had a heart burial at Tewksbury Abbey.
