The tomb of the House of Staufen in the central nave
The tomb of the House of Staufen stands out in the middle of the nave. The late Gothic sarcophagus, made by a sculptor from Göppingen, contains the monastery church's famous dead. Two of the four corner figures bear a model of the church. These are either the monastery's benefactors, Duke Friedrich and Agnes von Waiblingen, or their son, King Konrad III, and his wife Gertrud. The tomb slab displays the House of Staufen coat of arms with the famous three lions, which is now part of Baden-Württemberg's coat of arms.
