This is an underground limestone mine, which is rather strange, as most countries quarry limestone. But Finland is part of an old craton, crystalline and metamorphic rocks, with almost no younger sedimentary rocks. So there is little limestone found in the country and this deposit is valuable.


The Tytyri gruvmuseum (Tytyri mine museum) is located on the 110 m level of the Tytyri gruv (Tytyri pit). Beneath the typical tools and machinery, descriptions and documents of every day life of the miners, there is also an art exhebition underground. There is also a so-called adventure mine. The level of the museum is reached either by original mine wagon, a sort of funicular, or by a modern lift.

This mine is still working, today the miners work at the 350 m level. The network of more than 60 km of tunnels is crisscrossning under the lake and the town Lohja.

The mining at Lohja was stared in the 16th century with a permission by Gustavus Vasa, King of Sweden and Finland. But at first it was an iron mine. Then in 1897 limestone was discovered, which is actually not an ore. Nevertheless, Scandinavia lacks limestone an the rock is needed for various reasons, to make cement and concrete for example, or as a part of various indurstrial processes. So it was lucrative to mine the limestone, even underground which is much more expensive.

The limestone mine started with a quarry in 1911. In 1947 the crushing plant was erected in the mine below at 110 m and huge limestone blocks were dropped into the mine for crushing. In 1956 the oben cast mining was stopped and now all mining is underground.

In 2012 the mining museum was the location of a special event named Muru Pops Down in Tytyri. Muru restaurant was named Restaurant of the Year 2012 by the Finnish Gastronomic Society. They offer a four-course dinner in a mining canteen which is part of the museum. The menu is salted salmon seasoned with cumin and mustard-acquavit sauce, fennel risotto with escargots flambéed in Pernod and roasted veal tenderloin and hangar steak served with béarnaise sauce. The tickets for €128 include transportation to and from the mine from Helsinki.
