In the basement of the exhibitions, visitors can for the first time wander through a reconstructed cave made from 20 tons of crystals.
The crystals have been sourced from the limestone caves beneath Brevik and Eidangerfjorden. These caves hold some of the world's most diverse collections of calcite crystals.
The Crystal Cave exhibition is divided in three parts. In the two first rooms visitors can walk through the reconstructed mine cave with crystals, calcite variants and other minerals. In the last room are displayed spectacular fluorescent minerals from all over the world.
