+Graubünden is the biggest canton of Switzerland in which famous places are placed like: St Moritz and Davos. Nevertheless, its desolate mountain valleys and its pine forests, isolate and originate a certain ignorance of the zone for the foreign tourist.

This isolation has allowed that there should last the fourth official language of Switzerland: the romanche, a dialect of the Latin, in spite of the importance of the German. As contrast, St. Moritz is one of the most famous world ski resorts, place of elite and headquarters of two Winter Olympic Games, in 1928 and 1948.
