1590, a hospital for travellers was built at Urnerboden, with the maintenance of the pass shared between the cantons of Uri and Glarus. In 1625 Glarus transferred their section of the route to a private individual. In 1717, a chapel was built at the summit, probably dedicated to St. Nicholas of Myra. In 1870, a road was built from Altdorf to Unterschächen, and in 1893-99 the road was extended across the pass to Linthal. The building of the road required the demolition of the 1717-built chapel, and the current Bruder-Klaus-Kapelle was built in 1938.
