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 grotto was inaugurated in 1954. Until the end of the 1960s, a procession to the grotto took place every year on May 1st and August 15th. Beautifully designed and inviting place. There is more information about the history on the board on site. Definitely worth a visit!

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.
