This is not the only reason the cave is widely popular. Neanderthal tools were also excavated here dating back about 40,000 years, along with a few remains made out of quartz which is rarely found in Europe.
There is also the small church next to the cave entrance, built at the same spot where the original one was erected in 1809.
The Cave is 400 meters long, stretching onto two floors. The entrance is 3 meters wide with the path then narrows down into a small corridor, leading into a great hall.
