A burial against the rules
The grave of Rudolf I lies in the northeast corner of the chapter house, directly in front of the entrance to the Chapel of St. John. The sandstone slab of the crypt measures 174 x 72 centimeters. It has no decoration at all and lies flush with the floor. It is possible that this was done to disguise the violation of the rules of the order. It is documented that the crypt was opened several times over the centuries. When it was shut again, however, its slab seems to have been accidentally flipped over, meaning that its underside is now on top.
