REGAN Vest Cold War Bunker

A top-secret atomic bunker has opened to the public in Denmark. Built to withstand a nuclear attack, it's now an astonishing subterranean museum that sheds light on Cold War paranoia. Located 20 kilometers from the coast, this Cold War bunker was designed to house Danish government officials and military leaders in the event of a nuclear conflict. The facility, known as REGAN Vest, was constructed during the height of Cold War tensions and remained classified for decades.
