The Rhine Gorge, the Ruinaulta and the World Water Library

15 December 2023

The Rhine Gorge, also known as Rheinschlucht in German or Ruinaulta in Romansh, is a 400-metre-deep and 13-kilometre-long gorge located in Graubünden. It dates back to the great landslide of Flims, known as the Filmserstein-Bergstürz, which occurred approximately 9,500 years ago. Since 1977, the Rhine Gorge has been listed in the Federal Inventory of Landscapes and Natural Monuments of National Importance (BLN).

The landslide affected an area between Ilanz and Reichenau. A lake was formed, and the water of the Vorderrhein gradually made its way through the masses of stone and earth.

Numerous small peninsulas, islas, exist in the gorge. They were partly used as pasture, and arable land and settlements arose. The islas also have names: Isletta, Disla-Prau Grond, Isla Sura, Isla Sut, Islas da Bargaus, Isla da Corvs, Islas da Zir, Zir Grond, Zir Pign or Isla Davon.

Ilanz

Initially, passenger and goods roads did not run through the gorge but along its edges. They connected Reichenau-Tamins, Trin, Sagogn, Versam, Schluein, Ilanz, Castrisch, Flims, and Laax with Chur. With time, however, roads and bridges made the gorge accessible at several points.

The Reichenau-Ilanz railway line, opened in 1903, connected several villages, including Versam-Safien, Sagogn, Valendas, and Castrisch, with the more distant Disentis-Mustér. Subsequently, new roads and bridges were constructed in conjunction with the railway’s development and the rise in motor traffic.
