Set thirty meters (100 feet) underground, deep within the bedrock and in what was once used as a Swedish atomic bomb shelter, lies this high security internet center. What sounds like the perfect hideout for a CIA facility or a film set for the next Jason Bourne film, is actually the HQ for the Swedish internet server provider, Bahnhof. Named "Pionen, White Mountain," the internet service facility is centrally located in Stockholm, directly below the Sofia Church, where the cave-like formation houses server halls and offices.

The architectural firm behind this impressive transformation was Albert-France Lanord (AF-L), which was asked to treat the granite rocks as if they were a living organism. The idea was to bring human comforts from earth underground, such as plants, light, water and technology. "We created strong contrasts between rooms where the rock dominates and where the human being is a stranger against rooms where the human being took over totally," says AF-L. Daylight was obviously one of the biggest challenges for the architects, who designed a long tunnel, allowing for natural sunlight to filter through the underground space, with small buttresses to reflect the light into several zones.

The modest, single front entrance to the bomb resistant "Pionen" is protected by security 24/7. This high level of security provided by Bahnhof only seems fitting for Wikileaks founder Julian Assange, who according to the Daily Mail used the center in 2010 as a back-up server for the numerous confidential emails and documents in his possession.

Better than the bat cave. I am not naturally given to envy but man this place is awesome. The architects did a phenomenal job. They should expand it into a hotel too. They may have to be careful about mildew or other organisms with all the water, water misters, and plants. A coy pond or two would look cool in there. Perfect movie set for a variety of Sci-Fi or action movies. I bet they save a bundle on AC; well maybe not, it is in Sweden. In Arizona...

Too bad you can\'t excavate rock cheaply in the first place, that limits the potential of this sort of thing...there are only so many cold war bomb shelters and missile bunkers.


very cool datacenter, but propably the oldest news i\'ve ever seen on gizmag..

Sprinkle some glitter on the walls and it would look like a set for the original Star Trek series. Some parts remind me a bit of \"A Taste of Armageddon\".

Anyone else notice the floor of the hanging conference room is a picture of the moon?

Mindbreaker If you don\'t mind limestone it can be easily cut with a presser washer.
