The fortress was designed to house a garrison of over 300 soldiers in the event of an attack.
The underground tunnels span approximately 1.7 kilometers in total length.
The deepest part of the complex is situated 50 meters below the surface level.
It is one of the few Czechoslovak fortresses that were preserved as a memorial rather than being utilized for storage or industrial purposes.
The ventilation system is a highlight of the technical engineering, designed to maintain breathable air during prolonged artillery fire.
The complex includes a dedicated funicular rail system that was used to transport ammunition within the lower galleries.
Dělostřelecká tvrz Bouda is one of the five completed artillery fortresses of the Czechoslovak border fortification system constructed between 1935 and 1938. The site serves as a museum located in the Orlické hory mountains near the Polish border. It consists of five reinforced concrete structures connected by a massive underground tunnel network. Most of the original internal equipment and weaponry were removed during the German occupation in World War II, but the subterranean layout remains largely intact. Visitors explore deep-level galleries including barracks, ammunition depots, and command centers. The site is part of the K-S 22a 'Krok' fortress complex.
The exterior of the K-S 22a 'Krok' infantry casemate, which clearly illustrates the reinforced concrete design of the bunker.
Bring a warm jacket, as the underground temperature remains near 5°C throughout the year.
Wear sturdy, waterproof hiking boots suitable for uneven and damp ground surfaces.
Bring a headlamp or flashlight to better view the technical details in the unlit sections of the tunnels.
Do not attempt to access the fortress outside of guided tour groups, as the underground environment is complex and requires navigation expertise.
Open seasonally from spring through late autumn; usually closed during the winter months due to bat hibernation and safety conditions.
Maintain silence in memorial areas; do not touch sensitive historical hardware or graffiti from the 1930s.
