The Atomic Command Center, located in the Kampinos Forest, is a decommissioned military facility that was intended to serve as a command center in the event of a nuclear war. The construction of Complex No. 7215 began in the 1960s but was halted in the 1980s, primarily due to advancements in satellite technology. The facility consisted of three buildings connected by an underground corridor. The first was a three-story command bunker, disguised as a weather station, equipped with its own power generator and water supply system. The second building resembled a school and contained soldiers' quarters, a kitchen, and a dining hall. The third structure, a large underground hall, was only partially completed. After the complex was handed over to the National Park in 2004, it was partially looted, and in 2017, its above-ground buildings were demolished. The underground structures were repurposed as a bat habitat, and in 2019, the area was opened to tourists, featuring an educational trail. A cultural reference to the facility is Bartek Biedrzycki’s novel "Kompleks 7215," in which the site serves as a fictional NATO bunker. Interestingly, similar facilities can also be found in Złotkowo and in the former East Germany. The complexity and mystery of this place attract interest from both historians and architecture enthusiasts, making it an important relic of the Cold War and Polish military history.
