A military bunker located near Oslo, Norway, built during the Cold War era to provide protection against potential nuclear threats. The bunkers were constructed due to Norway's proximity to the USSR, and their restoration is currently underway. The facilities were designed to serve as secret bases and were intended to be used in the event of a nuclear attack.
Today, the bunkers are being repurposed and some have been sold to private individuals, raising concerns about the perceived survivability of nuclear war.
