The museum presents the history of the Cold War in the middle of the Zemaitija National Park.
Various artifacts from the Cold War era allow visitors to immerse themselves in the subject matter. It is the only exhibition in Europe which is located in a former Soviet underground ballistic missile launch shaft.
In the period from 1963 to 1978, four medium-range ballistic missiles SS-4 equipped with thermonuclear warheads were stationed here. The missiles, together with the nearby platforms of analogue missile launching, were capable of destroying all of Europe.
