Schöllenen Gorge (German: Schöllenenschlucht, or pronouncing the region: Schöllenen) is a gorge formed by the upper Reuss in the Swiss canton of Uri between the towns of Göschenen to the north and Andermatt to the south. It provides access to the St Gotthard Pass.
Enclosed by sheer granite walls, its road and railway require several spectacular bridges and tunnels, of which the most famous is a stone bridge known as the Teufelsbrücke (or Devil's Bridge).
The lower Urseren marks the boundary of the Aar massif with the autochthonous sediment of the Gotthard nappe ("Urseren-Zone"). In Altkirch quarry, on the southern end of the gorge, Triassic and Jurassic sediments are exposed. In the Schöllenen Gorge (at the Urnerloch tunnel), the Reuss enters the cristalline Aar massif (Aar granite), the gorge itself being an exemplary late alpine fluvial Water gap.
The name of the gorge is from Rumantsch *scalinae ("stairs, steps"); recorded in German as Schellenden in 1420. It formed the upper limit of Alemannic settlement in the Alps prior to the 12th century, and the border between the bishoprics of Constance and Raetia Curensis.
