That is what passengers see as they cross the Landwasser Viaduct on the Rhaetian Railway: their own locomotive swallowed by a tunnel portal carved into a sheer cliff face at the far end of a curving bridge 65 meters above the gorge floor. No approach ramp, no gentle transition -- just six limestone arches tracing an elegant curve through the air, then darkness. It is one of the most photographed railway structures in the world, and one of the few that looks more improbable in person than in pictures.

Alexander Acatos designed the viaduct, and the construction firm Muller & Zeerleder built it between 1901 and 1902 for the Rhaetian Railway. The technical achievement is remarkable for its era: the builders erected the structure without conventional scaffolding, relying instead o...

The last arch terminates against a vertical rock wall, and the tracks plunge directly into the 216-meter-long Landwasser Tunnel without any horizontal transition. The tunnel portal was deliberately aligned with t...

It does not cross the gorge in a straight line but arcs through it, following the geometry dictated by the tunnel alignment and the terrain. The dark limestone contrasts sharply with the green valley walls in summer and t...
