In 1997 the Danish Nature Agency acquired the Limestone Caves of Mønsted. The acquisition was directly caused by the owners closure of the caves in 1995 those having been open to visitors for many years.This was regarded as unfortunate by many people and the Danish Nature Agency initiated legal proceedings for protection and reopening of the caves. In the end the state took over the caves, the limestone factory and app. 10.000 hectares of land. In this way all interests in the property were considered. Above all the goal was to secure the caves as the most important hibernation site for bats in Europe but also to secure the cultural historical, the recreative and geological interests connected with the site.
