Lucerne’s Sonnenberg civil protection shelter marks 50 years
The Sonnenberg civil protection facility in Lucerne opened on 26 October 1976 as part of a road tunnel.
Built amid fears shaped by 20th-century wars, it was designed to shelter up to 20,000 people.
The site included a command post, an emergency hospital and other infrastructure, but a 1987 exercise exposed major problems with its plans.
After the Cold War, its role changed, and its capacity was reduced to 2,000 people in 2005.
The shelter has never been used in an emergency, while the tunnel remains an important road link.
For its 50th anniversary, visitors were given a tour, and Lucerne’s city archive shared photographs tracing the facility’s history.
The anniversary has renewed attention to how threats and civil protection plans change over time.
