|~1000||Denmark was christianized and the monks needed lime for building churches and had the knowledge how to produce it.|
|1860||the lime production was at its climax.|
|1872||the farmers of Mønsted sold the lime priviledges to the Mønsted Kalkværker.|
|1953||the limestone pits were closed.|
|1955||the limestone quarry was also closed. Now limestone from Djursland was burned in the limekiln.|
|1978||the lime industry in Mønsted ended.|
|1981||bought by the violinist Anker Buch who organized subterranen concerts.|
|1997||bought by Skovthe-og naturstyrelsen and reopened.|
|DEC-2006||Arla Foods recalled a shipment of cheese exported to Germany after detecting rats in the cave where the cheese was matured.|
In Mønsted a typical geological situation for the northern European flatlands provided the farmers a resource of value: limestone. It was burned in a lime kiln and used for many purposes: slaked to mortar for building churches, later the metal and chemical industry also bought the limestone and the agricultural industry used the limestone for the fields. The flint in the limestone was used as fillings in streets, foundations and brickwork.
The geological situation is typical for halotectonics. A little simplified it looks like this: a basement of crystalline rocks is covered by a thick layer of salt, which is covered by different sedimentary rocks. Salt is solid at the surface, but deep below other layers, under pressure, it is able to flow very slowly. And typically it is a little bit lighter than the surrounding rocks. So it starts to move upwards like gas bubbles in water (just a little bit slower). It forms huge diapirs and is able to press up the overlying rocks.
The result at Mønsted is very usefull: layers of limestone, which are normally much deeper, below deposits of ice age and other sedimentary rocks, are pressed to the surface by the salt. The limestone was mined in a quarry and several mines which followed the layer underground.
The extensive quarries are today used for various things. There are concerts and Halloween exhibitions, even art exhibitions have been made it the mine. Bat Safaris are special guided tours with emphasis on the bats. A part of the mine is used for an hourly multimedia presentation about the lime history of the area. And finally there is the special cheese, which is sold at the Café Grotten.
Probably the Grube Ost, the cave cheese, is the most impressive use of the mines, at least from the odorous view. The cheese spends eight weeks in the cave for maturing, while it is turned once a week. The 98% humidity and 8°C are the ideal conditions for this process. The result is a rather smelly cheese with intensive flavour, somewhere between Danbo and Emmental. Most of the cheese is sold to Germany named Arla Höhlenkäse (Arla Cave Cheese).
200 tons of cheese were stored in the caves by the small Vellev Mejeri (Vellev dairy), which produced 11,500kg cave cheese per day. Arla is the Danish and Swedish food company to which the Vellev dairy belongs, and Europe's largest dairy company. The small dairy at the village Vellev was very successful and won various prices for the cave cheese. But despite being successful, there are obviously some drawbacks in belonging to a huge food company. Together with three other dairies Vellev was closed in 2004, the production moved to Hjørring. At least the employes were given new jobs at the other dairies of the company. And the cheese is still produced in the caves.
