What is the 10-Z Bunker Brno Nuclear Shelter?

The 10-Z Bunker Brno nuclear shelter was once a classified military site. It was designed to protect the city's elite during a nuclear attack. The tunnels stretch deep into the rock beneath the famous Špilberk Castle. For decades, the public had no idea this massive complex existed.

Today, the bunker serves as a living museum and a unique hostel. The staff has preserved much of the original equipment, including diesel generators and air filtration systems. You can learn more about the history of the anti-nuclear shelter in Brno during your stay. The atmosphere is heavy with the weight of 20th-century geopolitical tension.

Staying here is one of the most unusual things to do in Brno. It appeals to those who want to step back in time. The facility is managed by a non-profit organization dedicated to historical preservation. Your stay directly supports the maintenance of this impressive technical monument.

The environment is the most striking feature of the stay. The temperature stays around 14°C (57°F) year-round. It feels damp, and the air has a distinct metallic scent.

Practical Tips for Your Stay in 2026

To reach the hostel, you can use the efficient Brno Public Transport system. The entrance is a short walk from the Husova street tram stop. If you are arriving from the airport, check the schedules on the official tourism portal. Booking in advance is highly recommended, especially during the peak summer months.

The low price point makes it accessible for almost any budget. You will leave with a deep appreciation for modern comforts and a better understanding of the Cold War.

However, if you prioritize a good night's sleep over a unique experience, you might find it difficult. The noise and cold are real factors that can disrupt rest.

It offers a similarly chilling atmosphere but allows you to return to a warm hotel afterward. Brno has many standard hotels that provide traditional comfort while keeping you close to the historical center.
