Festung Fürigen, Military fortress at Lake Lucerne shore, Switzerland

Festung Fürigen is a rock-cut artillery fortress at 436 m on the west foot of the Bürgenstock in Stansstad, Nidwalden. A 200-metre tunnel driven into the mountain holds two 7.5 cm gun positions, a munitions magazine, kitchen, hospital, offices and sleeping quarters. The rooms and fittings largely date from the construction period.

The fortress was constructed between 1941 and 1942 as part of Switzerland's defense strategy during World War II. It was designed to protect alpine routes and was one of several secret fortifications built across the country during that time.

The museum displays objects and stories from soldiers who were stationed here until the 1980s. Visitors can see personal items and accounts that show what daily life was like for those living and working in this underground installation.

The fortress lies on the road from Stansstad to Kehrsiten, at the foot of the Bürgenstock. The rock galleries are cool and damp, so bring a jacket and sturdy shoes. The site is one of three exhibition venues of the Nidwaldner Museum.

The facility was equipped with two 7.5 cm fortification cannons that could fire up to 15 rounds per minute. With a range of 12 kilometers (7.5 miles), these weapons could monitor a vast area of the lake.
