Monastery, today primarily known as the tomb and founding of the Staufers, has many patrons and donors. Two families were of particular importance for its further history. Especially active were the Knights of Woellwarth and the Knights of Schechingen, families of the low nobility from the region. They appeared increasingly as donors from the 13th century on. Family members repeatedly became abbots or assumed duties of the monastery administration. From the end of the 14th century the Woellwarths and the Schechingens buried their dead in the monastery church. For this purpose they used the transept of the church: in the North, in the Mauritius Chapel, the Woellwarths, and in the South, in the Bartholomew Chapel the Schechingens. The burials were, as was common in the Middle Ages, linked to donations and gifts to the monastery. In return for this the clerics of the Order regularly held church services for the salvation of the donors. This preserved the memory of the family dead.
In the 15th century the Woellwarths had their graves united in a proper sepulchral chapel. Since that time a wall has separated the transept, the Mauritius Chapel, from the rest of the church. New grave slabs were installed, and these were set up along the walls in some cases. The separating wall facing the square chancel did not fall again until the late 19th century, when the church was freed of built-in elements during the renovation work. The grave slabs of both families can still be found in the church today. The tombs are valuable art history testimonials to sculptural art of the late Middle Ages and the early Renaissance in Württemberg. Of particular interest to many visitors is the fact that one of the knights is portrayed as dead, partially decayed and inhabited by snakes and toads. Although a legend tells that this knight was the victim of a hunting accident and his body was first found in this state, the truth is far less dramatic. In the late Middle Ages it was a popular motif to humbly point out the transience of human beings - especially when the person concerned was among those who possessed power and wealth in this world.
