A beautiful, mystical place open to the public and hopefully kept clean by all visitors.

The Moritzloch is a large, oval, basin-shaped sinkhole that has collapsed into the uppermost shell limestone. At its deepest point in the northern part of the sinkhole (approximately 7 m deep), there is an artificially enlarged entrance to a karst cave. The cave is not accessible.

Sinkholes are funnel-shaped depressions in the ground created by the collapse of the overburden into subterranean cavities. The Waltershöhle is one such sinkhole. The shafts were formed when seepage water dissolved the limestone, creating cavities that later collapsed. Although legend has it that the Waltershöhle extends all the way to Rottweil, Walter Bürk, a Schwenningen resident after whom it is named, only managed to penetrate one and a half meters into the sinkhole opening.

This "Fatima Grotto" carved into the rock is dedicated to the Mother of God. It was named after the town of Fatima in Portugal, where Mary appeared several times to some shepherd children in 1917 (during the First World War). Our Lady revealed three secrets to the children. Pope John Paul II attributed his survival of the assassination attempt on him on May 13, 1981 - the commemoration of the first apparition of the Virgin Mary in Fatima - to Our Lady there. The bullet that almost killed him was later incorporated into the crown of the statue of Our Lady in Fatima as a votive offering.

Here you can see natural shafts where the underlying shell limestone was washed out by erosion.
