Callio Lab is a new environment for underground research and other activities. The laboratory is located in the Pyhäsalmi Mine which is a copper and zinc mine being the oldest operating mine in Finland and the deepest active hard rock mine in Europe with the depth of 1444 metres.

The infrastructure of the mine is excellent for various physics experiments due to the large rock overburden, but it can also serve for other fields of sciences, offering unique facilities and a wealth of  opportunities for a variety of scientific and commercial purposes.
