Cave under Bojnice Castle
This little natural travertine cave under the castle is part of the Bojnice castle tour. It is interconnected with 26 m deep castle well.
Bojnice castle stands on a travertine hill. As the castle's own water sources (precious resource that could have not be poisoned by enemies) gnew away the travertine, the cave obtained a circular shape and specific wall decoration. There are two lakes, probably linked to other underground spaces.
The cave originally served as a shelter for castle residents and also as a water reservoir. There is archaeological evidence that the cave was used during the Stone Age.
