The Falkenhagen Bunker is an abandoned semi-submerged military industrial complex located near Falkenhagen in Brandenburg, Germany. Originally constructed by Nazi Germany during World War II, the facility was designed for the production of N-stoff (chlorine trifluoride), a highly reactive chemical compound. The complex was never completed to its intended capacity before being captured by Soviet forces in 1945.
Today, the site stands as a decaying relic of wartime industrial ambition, offering a glimpse into the secretive military infrastructure of the Third Reich.
