Festung Klein-Durren, Military fortress in Obwalden, Switzerland.
The Festung Klein-Durren fortress features a two-story rock cavern and eight casemates designed for artillery installations at 1205 meters above sea level.
Built in 1942, the fortress served as a critical defense point during World War II and remained operational until its decommissioning in 1998.
The fortress represents Swiss military engineering excellence through its network of tunnels, which protected the strategic Rengpass mountain pass between Hergiswil and Alpnachstad.
Access to the fortress was initially through the Pilatus Railway from Alpnachstad, later supplemented by a military cable car system constructed in the 1950s.
The artillery positions within the fortress maintained a firing range extending from Bürgenstock to Buochs, supporting multiple 12cm cannons and 10.5cm fixed guns.
