Pioneen Center, Sweden

One of the most secret objects of Sweden is located in Stockholm, we are talking about the center "Pionen". The bunker was built during the Cold War as a shelter for the government, and later a secret complex began to be used as a data center. Currently, the center belongs to the Internet provider Bahnhof. To get to the place of storage of secret servers, you need to go through a long tunnel that goes deep underground.

Approximately, the bunker is located under the historical district of Stockholm, at a depth of about 98 meters. Today the most valuable military information of the state is stored here. In the underground storage, an autonomous power generation system was equipped, and one of the main features of the bunker is considered to be an incredible design. To make employees’ stay in a closed underground space more comfortable, it was decorated with living plants, beautiful underground waterfalls and aquariums.

Some employees are forced to stay in it for several weeks or even months. To make it easier for them to tolerate the absence of natural sunlight, a special system was integrated in the center that mimics the change of day and night. The old bunker is so reliable that it can easily survive even the impact of a hydrogen bomb. It is strictly prohibited to enter it. Numerous pictures of the "Pionen" centre allow to evaluate its ultramodern furniture. It makes the data center similar to an object from fantastic films about the distant future. Next - Yaman Tau
