Festungsmuseum Fortezia Stalusa

Festung Stalusa (Fortezia Stalusa) near Disentis/Mustér in the Surselva region of Graubünden is a Cold War-era mortar fortress built in 1967 and kept under strict secrecy for 40 years. The volunteer-run association now opens the works to the public for guided tours on the first Sunday of each month at 15:00, and offers special events in the surrounding alpine landscape.
