About the museum
The Langwies Viaduct of the Rhaetian Railway was built between 1912 and 1914 for the Chur–Arosa line. Hermann Schürch supplied the design; the contractor and chief engineer was Eduard Züblin, and the timber centering was built by the carpenter Richard Coray. With a main arch spanning 100 meters, the reinforced concrete bridge was, when completed, the largest and longest-spanning railway bridge of this type in the world; it is about 284 meters long and 62 meters high.
On the bridge's 111th anniversary, Arosa Tourismus, Arosa Kultur and the municipality of Arosa opened the Viadukt Museum in 2025. Instead of building a new museum, it uses several historic rooms around Langwies station: the waiting room in use since 1914, the station office, the shed, the former railway service storeroom and a walk-in pier of the access bridge. Also included is the painted facade of the former rectifier building, which served the power supply of the Arosa Line around 1930.
The stations explore the history of construction and technology, the people behind the building, early film recordings and the importance of the railway line for tourism in the Schanfigg. Hand-cranked cinemas, a sound room, Polaroid stations and a craft room invite visitors to take part. In the former schoolhouse, about a 15-minute walk from the station, a model at 1:25 scale shows Richard Coray's fan-shaped timber centering; in the converted attic, a changing exhibition runs each season.
