An "Alp" refers to a high elevation pasture frequented only in summer. It often includes several huts and small places of worship (here the Alpe Bardughè in Ticino).
The Alps extend in an arc from France in the south and west to Slovenia in the east, and from Monaco in the south to Germany in the north.
