Sperrstelle Beatenbucht, Military fortification in Sigriswil, Switzerland
The Sperrstelle Beatenbucht contains an infantry bunker built into a rock cavern with a 15-meter-long tunnel and weapon observation slots.
The fortress was completed in January 1941 and handed over to the local defense force of Merligen in April 1942 during World War II.
This defensive position represents Switzerland's military engineering and strategic planning for protecting the nation's mountain passes and lakes.
The infantry bunker offers guided tours on fixed dates where visitors can learn about its wartime functions and explore the preserved installations.
The bunker featured a 4.7 cm infantry cannon that was later replaced with a 9 cm anti-tank gun capable of firing 8 to 10 rounds per minute.
