The Atomic KGB Bunker, also known as Atominis Bunkeris, is a Cold War-era nuclear bunker located in Kaunas, Lithuania. Situated 6 meters underground, this former Soviet military bunker has been transformed into a unique museum showcasing over 1,200 functioning exhibits related to the Cold War era. The museum houses the largest collection of gas masks in the Baltics, including specialized masks for adults, children, and even horses, providing visitors with an immersive experience of Soviet-era military preparedness.
The bunker was originally constructed by the Russian army during the Cold War as part of Lithuania's strategic defense infrastructure. Today, it serves as both a historical monument and an educational attraction, offering insights into the secretive world of Soviet military operations, surveillance techniques, and civil defense measures. The extensive collection includes authentic KGB and NKVD artifacts, spy gadgets, and communication equipment, making it a significant site for understanding the military history of the Baltic region during the Cold War period.
