The grave tomb of Queen Margrethe of Denmark (c. 1230 – 1282) with carved oak sculpture in the Münster in Bad Doberan. This is the oldest female grave tomb in any Cistercian church in Europe and the oldest tomb sculpture in Mecklenburg-Vorpommern. Her life was even more interesting. Margaret Sambiria was the daughter of the Duke of Pomerania and Matilda of Mecklenburg. She became Queen of Denmark when her husband became Danish King Christoffer I (1219-1259) in 1252 through the principle of agnatic seniority.
