Memorial to Lady Dervorguilla (d. 1289) who founded the Cistercian Abbey at Sweetheart (Dumfries and Galloway, Scotland) in memory of her late husband, John Balliol (d. 1268), and it was one of a number of charitable acts her performed in his memory. Following the death of her husband, Dervorguilla had his heart embalmed and placed in a silver and ivory casket which she carried with her at all times. When she died in 1289 she was laid to rest, with the casket, in front of the High Altar of the abbey church. The monks chose to name the abbey Dulce Cor or ‘Sweetheart’ in honour of her memory. John Balliol was a generous benefactor himself. During his lifetime he founded Balliol College in Oxford, which Dervorguilla continued to endow after his death. Dervorguilla is best known as the mother of John Balliol (d. 1313) who was set on the Scottish throne in 1292 at the behest of King Edward I.
