A Cultural Excursion: The Viaduct Museum in Langwies
During your stay at Hotel Altein Arosa, why not step into a piece of Swiss railway history? Just one stop away by train, the Viaduct Museum Langwies opens its doors for the very first time in summer 2025.
The museum brings to life the story of the legendary Chur–Arosa railway line and its crown jewel, the Langwies Viaduct. Once the largest reinforced concrete railway bridge in the world, it remains an engineering marvel to this day. Visitors can explore original station rooms – the waiting hall, the freight shed, even the old station office – each showcasing a different aspect of the railway’s past.
Interactive exhibits keep the experience lively: early railway films can be cranked to life in a miniature cinema, a sound room immerses you in the noises of the line, and in a highlight for many, you can even walk into one of the viaduct’s mighty concrete pillars. Families will enjoy the playful touches too, including a children’s puzzle booklet and Polaroid stations for keepsake snapshots.
For a special moment, time your visit to the viaduct pillar when a train is crossing overhead – a short window of a few minutes, but an unforgettable experience.
