An urban explorer has discovered what appears to be the deepest nuclear bunker in the world – with room for over 2,000 people.
Karsten, a content creator, found the Cold War bunker under a Eurpoean capital.
He claims it was built in 1952, at the same time as the city’s subway so no one would notice.

“The bunker was designed for 2,200 people with an area of 3,500-3,800 square metres,” the content creator, from Germany, told What’s The Jam.
“It was completed between 1962 to 1963.
“It was also equipped with a ventilation system that could filter 4000 cubic meters of air and radioactive dust.
“A water tank of 150 cubic metres was also placed in there, as well as a generator that was able to generate 30 kW of electricity.

“A huge emergency exit was also created, which was also built for ventilation.
“The bunker was never used and was kept ready until the mid-1970s in case of a nuclear war.”
Karsten says exploring the bunker was daunting but rewarding.

He said: “It was extremely scary.“Anyone with claustrophobia is definitely out of place down there.
