Graubünden (German; also called the Grisons in English) is the largest and easternmost canton of Switzerland. The German name contains the character ü and is sometimes written as Graubuenden when the diacritic is unavailable. The canton lies entirely within the Alps and is noted for its rugged mountain scenery, high passes and extensive tourism infrastructure.

Overview and geography

Graubünden covers a broad Alpine territory with deep valleys, high peaks and major watersheds. It contains the sources or upper valleys of important rivers and is home to the highest summits of the Eastern Alps, including Piz Bernina. Much of the region is sparsely populated, with the capital at Chur and well-known resort towns such as Davos and St. Moritz.

Languages, culture and administration

The canton is officially multilingual: German, Romansh and Italian have recognized status in different areas. Romansh, a Romance language of the Rhaeto‑Romanic branch, survives here as a regional cultural marker. Administratively, Graubünden is divided into smaller local units and regions that manage services across scattered mountain communities.

History and identity

The modern canton grew out of medieval alliances often called the Three Leagues, which united local communities for mutual defense and autonomy. These league structures influenced Graubünden's distinctive local governance and later integration into the Swiss federal state during the period of Napoleonic and 19th‑century reorganization.

Economy and importance

Tourism is a major economic pillar: alpine skiing, hiking, spa resorts and international events draw visitors year‑round. Hydroelectric power, forestry and mountain agriculture also contribute. The canton has notable rail routes and mountain passes that connect north–south and east–west across the Alps.

Notable features and attractions

  • World‑famous resorts: St. Moritz and Davos (the latter hosts major international meetings and conferences).
  • Scenic railways, including UNESCO‑recognized routes that traverse high alpine landscapes.
  • Multilingual communities where German, Romansh and Italian traditions coexist.
  • Rich network of mountain passes and valleys that support outdoor recreation and seasonal tourism.

The alternative spelling Graubuenden is still used in contexts where the umlaut is not available.
