The Engadin or Engadine is a long high Alpine valley region in the eastern Swiss Alps in the canton of Graubünden in southeasternmost Switzerland with about 25,000 inhabitants. It follows the route of the Inn from its headwaters at Maloja Pass in the southwest running roughly northeast until the Inn flows into Austria, little less than one hundred kilometers downstream. The En/Inn subsequently flows at Passau into the Danube, making it the only Swiss river to drain into the Black Sea. The Engadine is protected by high mountain ranges on all sides and is famous for its sunny climate, beautiful landscapes and outdoor activities.

Romansh is a Gallo-Romance language spoken predominantly in the Swiss canton of the Grisons (Graubünden). Romansh has been recognized as a national language of Switzerland since 1938, and as an official language in correspondence with Romansh-speaking citizens since 1996, along with German, French, and Italian. It also has official status in the canton of the Grisons alongside German and Italian and is used as the medium of instruction in schools in Romansh-speaking areas. It is sometimes grouped by linguists with Ladin and Friulian as the Rhaeto-Romance languages, though this is disputed.
