The Atom Museum Javor 51 is a unique museum of nuclear armaments located in an underground bunker between the villages of Míšov and Borovno in Brdy.

The entire building, a former Soviet nuclear ammunition depot, is a well-preserved technical unique and a treat for bunker lovers and military history buffs. The exhibition will give a glimpse of the time when East and West were preparing for a possible nuclear conflict. Today, it embodies the stifling atmosphere of the Cold War. Construction of the Javor 51 Borovno military facility began in 1965.

The bunker occupies an area of 1,600 square metres and includes a hall where nuclear warheads were stored. Each hall is dedicated to something. The first hall to the Cold War, the second to the Soviet atomic programme, the third to the American atomic programme and the fourth to the peaceful use of nuclear energy.

In the museum there is a nuclear mine that weighs about 80 kg. It was to be used for so-called nuclear underground construction. Hundreds of mines were made on both the east and west sides. They were buried 200 metres underground at crossings along the so-called Iron Curtain and were controlled remotely by radio. If troops moved from either side, they would be detonated. This would create a cavern up to 300 metres in diameter underground, which would collapse and create a large crater up to 50 metres deep, and no equipment would get through.

Depot 10B, the only nuclear munitions storage facility in the world open to visitors. It used to be the most guarded and secretive place in the former Czechoslovakia. The unique museum exhibit documents the development of nuclear weapons since 1945, including a model of the plutonium bomb used at Nagasaki. A section is dedicated to the meaningful use of nuclear energy. Depot 10A opened for the first time on 21 May 2022, when the Energy and Civilisation exhibition was installed in its first cubicle. Next year, it will house an exhibit dedicated to space, astronautics and UFOs, with new documents declassified by the US Congress. The entire exhibition will then be entitled "From the Atom to Space...and Back to Man".

Other unique features include a recently declassified order signed by an American major to drop an atomic bomb on Hiroshima, pictures and a bell from the church in Sarov, a center of Soviet nuclear research.


Exposition of Space, Cosmonautics and UFOs (2023)
In 2023, the Atomic Museum is to create an exhibit dedicated to space, cosmonautics, and UFOs, featuring new documents declassified by the U.S. Congress. The entire exhibit will then be titled "From the Atom to Space...and Back to Man." depot 10A will feature space, images from telescopes, and flights to the moon and Mars.
