This family living in the United States bought a new property, so they started to explore every inch and every corner of the estate. While walking in their back yard, the family discovered something that appeared to be a secret hideout or an underground shelter. But when they opened the big metal door, the family realized that a piece of history was unfolding in front of them.
The hideout was actually a bunker built during the Cold War between the United States and the Soviet Union! The bunker was filled with food supplies and other things that remained intact since the 1960s.
