Caves have fascinated people since ancient times. Caves have been used for different kinds of reasons; for protection, as religious places, and for funerals. Today, one can learn about our ancestors who lived in and used the caves and also about how the climate has changed over the years.

The main chamber contains some of the world’s largest natural crystals ever found in a cave – where the largest had a length of 11 meters and a weight of 55 tons. Thanks to the heat inside the cave, the crystals have been able to become that big!
