Designed by Alexander Acatos, the Landwasser Viaduct was constructed between 1901 and 1902 by Müller & Zeerleder on behalf of the Rhaetian Railway, which both owns and operates it through to the present day.

The Landwasser Viaduct, composed of dark limestone, forms part of the Albula Railway section between Tiefencastel and Filisur, and is at the 63.070 kilometres (39.190 mi) mark from Thusis.

One of the striking features of the Landwasser Viaduct is its highly pronounced curve, which has a radius of 100 metres (328 ft), the minimum used throughout the whole railway.

[5] The viaduct's masonry is approximately 9,200 cubic metres (12,000 cu yd) in volume and is jointed with dolomitic limestone.

[10] The Landwasser Viaduct briefly appears as a bridge which was destroyed by Rasputin's minions in the 1997 animated film Anastasia.

[11] Since 2008, the cultural importance of the railway, and features such as Landwasser Viaduct, has been formally recognised by UNESCO, having been placed on a World Heritage list.
