What is Mønsted Kalkgruber used for today?
Mønsted Kalkgruber, located south of Hjarbæk Fjord and west of Viborg, has a long history as a workplace where lime has been extracted for construction for many centuries. Today, however, the mines have been transformed into a multifunctional area where both industry and culture thrive side by side. Although lime extraction ceased in 1956, Mønsted Kalkgruber remains an active and vibrant place with many different functions.
A tourist attraction and nature reserve
Today, Mønsted Kalkgruber is primarily known as a popular tourist attraction, where visitors can explore the fascinating underground tunnels. With its more than 60 km of mine tunnels, the mines are a unique place to experience. There are lighted areas in the mines, allowing visitors to wander through the historical caves and gain insight into the centuries-long limestone extraction, which was once the backbone of the local economy.
In addition to the geological and historical value, Mønsted Kalkgruber is also an important nature reserve. The mines serve as winter dens for thousands of bats which take advantage of the constant temperature and high humidity within the mines. The cool environment makes it an ideal place for bats to hibernate, which is one of the reasons why the area is protected as an important habitat for the bats. In addition, cultural events are regularly held in the pits, such as concerts, which take advantage of the natural and impressive acoustic conditions in the large chambers.
Maturing Cheese Underground
Although lime extraction has long ceased, Mønsted Kalkgruber is still used for industrial purposes. The Danish food giant Arla has rented part of the mines to mature their famous “Grubeoste” (mine cheese). The unique climate of the mines, with a constant temperature of 8 degrees Celcius and a humidity of around 98%, creates optimal conditions for cheese maturation. For three weeks, the cheeses are stored in the cool mine tunnels, where they are turned regularly to achieve the desired consistency and taste.
Maturing in the limestone mines gives the cheeses a characteristic taste, which is particularly popular in the German market, where the majority of the production is exported to. The unique use of the old mine tunnels demonstrates how a place with a rich history can adapt to modern industry and continue to contribute to both the local and international economy.
