The Secret History of the 10-Z Bunker Nuclear Shelter

The story of the 10-Z Bunker nuclear shelter began during World War II. It was first built as a civil defense shelter to protect people from Allied bombing. The Nazi forces used the natural rock of the Špilberk hill for protection. After the war, the site took on a much more secretive role during the Cold War era.

The communist government converted the space into a high-tech nuclear shelter. It was meant to house up to 500 people who ran the city and region. These individuals were the political elite who would manage the aftermath of a nuclear strike. You can learn more about this era in the history of civil defense shelters in Brno.

For decades, the bunker remained a secret known only to a few. It was fully functional with its own power source and air filtration systems. The site was finally declassified in the early 2000s. Since then, it has become a major attraction for those interested in the darker side of history. It remains a powerful symbol of a divided Europe.

What to Expect During Your Visit

Walking into the 10-Z Bunker nuclear shelter is a sensory experience. The first thing you will notice is the temperature, which stays at 14°C year-round. It feels damp and smells slightly of old machinery and diesel. This atmosphere is intentional, as the museum keeps the space as authentic as possible.

The museum uses a modern approach to tell its story. Instead of long text panels, you use QR codes on your phone to watch videos. These videos show former employees and historians explaining how the bunker worked. You will see the original diesel engine that powered the facility and the complex air filters. The narrow corridors are filled with original furniture and gas masks.

One highlight is the "Milk Bar" located at the entrance. It serves retro snacks and drinks in a setting that feels like the 1970s. You can sit on old chairs and enjoy a coffee before heading into the tunnels. The entire experience is designed to make you feel like you have stepped back in time. It is a chilling yet fascinating journey into the past.
