This was created as part of a Stations of the Cross at St. Bartholomew's Church, but the Stations of the Cross were never completed. The rock niche was chosen at the time to recreate the tomb of Jesus. Anyone looking through the bars into the tiny grotto will see a stone tomb surrounded by flower baskets.

The Wieslett and Horstmann tunnels are well hidden in the forest, a little off the main path. You can enter it at your own risk. No idea how deep it is accessible as I didn't have a flashlight with me to check.
