Please do not deface it!!! Below Hartenstein Castle lies the Gudenus Cave, which was carved out of the riverbank and inhabited by Neanderthals during the Stone Age. Traces of settlement dating back almost 100,000 years were discovered there, including hand axes and other tools. Due to historical preservation, the bridge could no longer be rebuilt unless the cave was sealed.

An impressive natural monument. The climb, approximately 15 minutes and 85 meters in elevation, is well worth it. The Stone Hall is part of the Kremstal Canyon, a region with other interesting caves such as the Gudenus Cave and the Eichmayer Cave. A 30-meter-wide and eight-meter-high rock roof. This sheltered site was frequented by Ice Age hunters. Neanderthal stone tools from the Middle Paleolithic and the end of the last Ice Age were found here.

In the immediate vicinity of the Bründl Chapel is a cave that is associated in folk tales with the robber chief Johann Georg Grasel (1790–1818), who is said to have used it as a hideout. However, historical evidence for this is lacking.

Stone caveFun for children. The stone cave on the way to the ladder to heaven is the first project of the Schrems Nature Park Association chairman Martin Speychal. In keeping with the region, it is built from solid Schrems granite and painted inside with Stone Age images. A low, S-shaped passage leads through the cave. [unterwasserreich.at]
