Oberheinzenberg exploration route

The Glaspass and Oberheinzenberg were settled in the 14th century by the Walser from Safiental. The dispersed settlement Tschappina with the districts Ober- and Untertschappina, Obergmeind and Inner- and Ausser Glas was until the late nineteenth century the only German-speaking community on the Heinzenberg. Oberurmein with the idyllic Patrutgsee, on the other hand, developed as a holiday home settlement in the 1970s and is a district of the municipality of Urmein.

For centuries, the Glaspass was the gateway to the outside world for the inhabitants of Safiental. They crossed the Glaspass to Thusis to buy groceries and other goods at the market and to sell their cattle. Only with the construction of the access road in 1885 from Thalkirch to Versam did the valley open to the north and the importance of the Glaspass declined.
