San Bernardino is a mountainous village in the canton of Grisons in Switzerland. It is the southern entry point to the San Bernardino tunnel, which complemented the road over the San Bernardino Pass in 1967, opening a new all-year-round road to crossing the Alps.
The village is part of the municipality of Mesocco. The language spoken is Italian, one of the three official languages in the canton of Graubünden.
The church dates from around 1450, only years before the Viamala gorge bridge was opened for traffic, multiplying traffic across the pass.
