The largest and easternmost canton of Switzerland, it is also one of the three large southern Alpine cantons, along with Valais and Ticino. It is the most diverse canton in term of natural and cultural geography, as it encompasses both sides of the Alps and several natural and cultural regions. The diversity of the canton is often compared to that of Switzerland and warrants it the name of "Little Switzerland". The Grisons is bordered by four cantons: Ticino to the south; Uri to the west; and Glarus and St. Gallen to the north. The canton is also bordered by Liechtenstein to the north; Austria's federated states of Vorarlberg and Tyrol to the north and east; and Italy's autonomous province of South Tyrol and region of Lombardy to the south.
