Mønsted Kalkgruber is one of the world’s largest limestone mines, made from sheer force and pick axes, a complex system of dark labyrinths and adventurous trails where thrilling discoveries await. Unlike any other attraction in Denmark, this is a trip that will take you far below the surface of the Earth into a Cathedral-like setting, where bats lurk in the darkness and a spectacular underground cinema lets you in on all the facts. Entering Mønsted Kalkgruber is like stepping into a world of fantasy where one might expect a few dwarfs to stop by with golden artefacts.
