This after-hours adventure tour leads through the hunting lodge of the “Soldier King” Friedrich Wilhelm I, who visited with his family every year for the so-called “Herbstlust”. Visitors encounter unexplained sounds such as rattling chains and eerie shadows, and notice that objects in the castle seem to move overnight. Along the way they meet giant spiders and bats, skeletons and skulls peering from dark chests, and ghostly figures slipping silently through the corridors.
