Bouda, Artillery fortress museum in Těchonín, Czech Republic.
Bouda is a 1930s military fortification comprising five combat structures linked by an underground tunnel network. These passages stretch over two kilometers (1.2 miles) beneath the Orlické Mountains and form an intricate subterranean complex.
Built between 1936 and 1938, this fortress served as part of Czechoslovak border defense during a period of rising tension. The structure was abandoned after occupation in 1938 and never modified, preserving its original design intact.
This fortress shaped how people understood Czech military self-reliance during the interwar period. The structure reveals how communities on the border maintained readiness through coordinated defensive architecture rather than isolated strongholds.
Tours guide visitors through the tunnel sections and typically last around one hour while exploring the subterranean passages. Interior temperatures stay cold year-round at about 5 degrees Celsius (41 degrees Fahrenheit), so bring a jacket regardless of season.
The K-S 22a Krok entrance shelter is the sole surviving example of this particular access design in the Czech Republic. This concrete structure demonstrates how engineers built entry points to shield them from hostile fire.
