Obersaxen (Romansh: Sursaissa) is a municipality in the district of Surselva in the Swiss canton of Graubünden. Obersaxen is first mentioned in 765 as Supersaxa though this is from a copy which dates from later. In 956 it was mentioned as Supersaxa, and in 1227 as Ubersahse. The current settlement was founded in the thirteenth century, when a group of German-speaking Walser settled the plateau. Right in the heart of the mainly Romansh-speaking Surselva (which encompasses the valley of the Vorderrhein, along with all of its side valleys, among others the Val Lumnezia), Obersaxen is an island of German speakers.
