The highlight is incorrectly placed. The grotto is directly on the other side of the monument.

The Felsenkeller is located near the Hoch-Altstätten Castle, a cave with a spherical diameter of about 3 m that was created by human hands and was probably used for storage, unfortunately there are no more doors. "Easy to reach on paths and supply roads from Altstätten, Marbach, Ober Lüchingen or St. Anton ..." also a fantastic mountain bike tour!

A small cave in the rock, possibly an earlier cellar. Protected by a double gate, one side of which, however, was torn off its hinges. Inside a curve with a diameter of about 3m, as well as in height.

The cave is a little hidden, but with the GPS you have to look for a hole in the floor, not a wall entrance. A rope was attached to the entrance through which you can slide down a good 20m. However, due to the difficult underground, I didn't dare to go any further, but it seems to go further. The cave is extremely slippery, even in hot weather, and good shoes, sturdy pants and good gloves are required to go just a few meters into it! CAUTION AND SECURITY ARE REQUIRED! Don't go in alone!

A wall in the rock is bricked up with an old door, the door is open, behind it a small unused rock cellar. Not very exciting.
