Rappenstein Castle Ruins
Built around 1250
Cave castle. Strong wall with window slits and high entrance. Remains of wooden beams mark the position of the arbours and external stairs leading to the high entrance. Remains of beams on the top of the wall hint at a roof construction or a wooden upper section. The interior of the cave is largely filled with rock debris. A narrow gap at the foot of the outer wall makes it possible to climb inside the cave.
