History of Luolakallio

The Luolakallio cave was built at the turn of the 1960s and 1970s for the needs of the Finnish Defense Forces and Posti-Tele. In 2009-2019, event activities were produced in the cave.

The circle closed in a way at the end of 2019, when four Finnish IT companies bought Luolakallio Oy’s share capital and the cave for the production of computer room services, i.e. for the purpose for which it was built during the Cold War.
