Sentralanlegget is the war headquarters of the Norwegian government. The facility is located in Hole municipality in Buskerud County, and designed as an underground shelter in the west side of the mountain Kongens utsikt. The purpose of this is to avoid a direct hit from a nuclear missile from the east.

1. History
Sentralanlegget was built by the civil defense authority during the 60s. The cold war and the threats represented by the Soviet Union made it necessary to build a facility where members of the Norwegian Royal Family, members of the government and other key personnel could evacuate to in case of a military attack on the nation. Hole municipality was chosen due to its massive mountain range, ideal for an underground shelter, and because of its relative proximity to the governmental offices and the Royal Palace in Oslo. The end of the Cold war marked a change in the threats against Norway, as the neighboring Soviet Union no longer existed. Seen in the light of the modern world, this facility is now in many terms outdated. Nevertheless, it is still operative and can be used if the situation should prove it necessary. During the 80s the Norwegian government built a new, smaller and more modern war headquarter in a bunker under the governmental offices in Oslo. This, though, can not accommodate a larger number of persons for a longer time.

2. Function
Sentralanlegget has two main entrances located some three hundred meters apart. From these, tunnels lead to the facility inside the mountain. The facility can accommodate 600 persons for months, and includes a hospital, restaurant/bar, communication central, conference rooms, situation room, private rooms for members of the government and the royal family and storage rooms for supplies. The facility is self-contained with power, water, air and food. It is the Directorate for Civil Protection and Emergency Planning that is responsible for the daily operation of Sentralanlegget. The Ministry of Justice and the Police and the Prime Ministers Office are also involved.

3. Secrecy
Due to the sensitive nature of such a facility, location and technical details are classified. The entrances are digitally removed from aerial photos in Norwegian internet search engines. During the 80s, journalists in a newspaper for a leftist non-violence organisation were threatened with legal action by the Prime Ministers Office if they published a story on the facility. In April 2010, the Norwegian Broadcasting Corporation reported that phone numbers, address, and the number of employees could be found in Norwegian search engines and telephone books. All information was provided by the Directorate for Civil Protection and Emergency Planning, most likely caused by a human error. Journalists also found technical drawings and lists of security cleared personnel lying open for everyone in the Norwegian state archive. These were later withdrawn.
