Festung Naters
The Festung Naters in Naters, Switzerland, is a former artillery fortress built in 1939/1940 that protected the strategically important Simplon Pass and Simplon railway tunnel. Today it houses the Gardemuseum (Swiss Guard Museum), which opened in November 2006 in the former ammunition halls. The museum presents the history of the Pontifical Swiss Guard through a permanent exhibition and a 'treasure chamber' with personal objects donated by guards and their families. The fortress, which could house up to 200 men, is like a small underground village and also hosts changing temporary exhibitions.
