Built 60 meters underground into a bed of limestone, this declassified (NATO Cosmic Top Secret) nuclear bunker from the Cold War was meant to house the Danish monarch and government as a last bastion of democracy in the event of a nuclear apocalypse.
The bunker is hidden deep in the Rold Forest in northern Jutland, hundreds of miles from Copenhagen. Its existence was kept a secret for many decades, and only revealed to the public in 2012. It opened as a museum in February 2023.
Construction started on REGAN Vest in 1963. It took some five years to built a bunker that was capable of withstanding nuclear war. The end result covered 5,500 square meters and was made up of more than 230 rooms capable of holding around 350 people.
