The tunnels were excavated by forced laborers and prisoners of war to protect strategic German aeronautical research from Allied bombing raids.
The facility was designed to house research offices and production workshops for the Arado Ar 234 jet bomber development.
Local geological surveys suggest the underground complex in Kamienna Góra is only a fraction of a much larger, partially collapsed or sealed network.
The temperature inside the tunnels remains constant at approximately 7-8 degrees Celsius year-round, regardless of external weather.
Many of the exhibits were sourced from local recovery operations and private collections specializing in mid-century military technology.
Projekt Arado is a subterranean museum complex located in Kamienna Góra, Poland, centered on the remains of a secret World War II German research facility. The site features an extensive system of tunnels and chambers once linked to the clandestine V-weapons program, specifically the Arado Flugzeugwerke aircraft design firm. Visitors follow a guided route through reinforced concrete bunkers and restored military infrastructure. The museum highlights the historical context of the Project Riese construction efforts in the Sudeten mountains. Displays include authentic German military equipment, documentation, and reconstructed laboratory spaces. The site serves as both a historical preservation project and an educational center focused on the industrial history of the Third Reich.

Bring a warm jacket or fleece as the underground temperature is consistently cold even during summer.
Wear comfortable, flat-soled shoes with good grip, as the tunnel floors are uneven and occasionally damp.
Book a guided tour in advance during peak summer months to ensure entry with an English-speaking guide.
Do not attempt to explore beyond the marked visitor paths, as the tunnels are not fully stabilized and lack lighting in restricted zones.
Open daily throughout the year, but guided tours are mandatory for safety.
Maintain proximity to the guide for safety reasons; touching artifacts is strictly prohibited.
