Norway is selling its NATO-funded secret submarine hideout, officially titled the Olavsvern Naval Base. Located off the Northern Coast, the whole unit (which includes a sub docking station, elaborate Austin Powers-like tunnel systems and office space) for only $17.5 million.

The above ground property is a sprawling 38,000 square feet and houses office buildings, residential suites, a workshop and a warehouse. But the real meat is located inside the side of the mountain. The sub base houses a dry dock (so you can take in your subs) an emergency power system, the previously mentioned tunnels and fuel cells. The base was used during the Cold War by American submarines that were on assignment in the Arctic Ocean. But according to TV2 Olavsvern has been reduced to a supply base.
