What to Expect Inside the 10-Z Bunker

Walking into the 10-Z bunker feels like stepping back into 1950s Czechoslovakia. The air is cool and carries a distinct metallic scent. You will explore a network of narrow tunnels carved directly into the hillside beneath Spilberk Castle. The lighting is dim, which adds to the authentic, slightly eerie atmosphere of the facility.

The tour is largely self-guided, allowing you to move at your own pace through various rooms. You will see original diesel generators, air filtration systems, and communication hubs. Many exhibits are interactive. You can touch the equipment, sit at the desks, and even try on vintage gas masks for a photo.

One of the highlights is the "Milk Bar" located near the entrance. This retro cafe serves snacks in a setting that looks frozen in time. There is also a small hostel inside the bunker. Staying overnight is an option for those who want the ultimate Cold War experience in 2026.

Best for: History buffs, solo travelers, and fans of industrial aesthetics.

Practical Details: Prices, Timing, and Booking

Planning your visit is straightforward. In 2026, tickets for the 10-Z nuclear bunker tour typically cost between 180 and 260 CZK. Discounts are usually available for students and seniors. You can purchase tickets at the entrance, but booking online is recommended during peak summer months.

The self-guided tour usually takes about 60 to 90 minutes. If you stop to read every display and take photos, you might stay longer. The bunker is open most days, but always check the official Go To Brno portal for holiday closures or special events. This ensures you have the most current information before arriving.

To reach the bunker, head toward Husova street. It is a short walk from the main square. You can also use the excellent DPMB - Brno Public Transport system to get close to the Shpilberk hillside. Look for the heavy steel doors set into the rock wall.

Comparing 10-Z to Other Brno Underground Sites

Brno is famous for its extensive underground network. The 10-Z nuclear bunker tour is the most modern of these sites. While the St. James Ossuary focuses on the macabre history of the 17th century, 10-Z focuses on the 20th-century political climate. Both are fascinating but offer very different vibes.

If you enjoy 10-Z, you might also like the Capuchin Crypt mummies guide. Both sites deal with the "hidden" side of the city. However, 10-Z feels more like a technical and political exploration. It provides context on how the city prepared for a nuclear conflict that never came.

For those who want a break from the dark, consider visiting hidden modernist architecture in Brno. It provides a great contrast to the cramped, utilitarian design of the bunker. Seeing both gives you a complete picture of Brno's architectural evolution.

Essential Tips for Your Bunker Visit

Even in the height of summer, the bunker remains cold. Wear a light jacket or a sweater to stay comfortable during your 10-Z nuclear bunker tour. The floors can be uneven in some sections, so sturdy walking shoes are a must. Avoid wearing flip-flops or high heels.

Photography is generally allowed and encouraged. However, be respectful of other visitors in the narrow corridors. If you are visiting with children, keep them close. The bunker has many heavy doors and technical artifacts that require careful handling. It is a safe site, but it is not a playground.

After your tour, take a moment to explore the surrounding area. The bunker entrance is near the path leading up to Spilberk Castle. It is a perfect spot to transition from modern military history to medieval fortifications. You can find more hidden spots in Brno just a few minutes away on foot.
