A military bunker located near Władysławowo, Poland, likely dating back to the Cold War era. The structure is part of a network of clandestine sites that were once home to hundreds of nuclear warheads, a secret kept from the country's people. The bunker's entrance has been unblocked by explorers, allowing for limited access to the site.
Poland's State Archives continue to digitize and publish records online, shedding light on the country's military history and the role these bunkers played during the Cold War period.
