Landwasser Viaduct
The Landwasser Viaduct is a UNESCO World Heritage site located close to Filisur in the canton of Graubünden, Switzerland. The Landwasser Viaduct is a limestone railway viaduct constructed in 1902 and it has supposedly appeared over one million times on postal stamps since then. The Glacier Express which runs from Zermatt to St. Moritz runs over this and many other viaducts on it’s magnificent journey.
