Locarno, Switzerland.
Madonna del Sasso.

The Madonna del Sasso is a sanctuary in Orselina above the city of Locarno in Switzerland. It is the principal sight and goal of pilgrimage in the city.
The founding of the sanctuary goes back to a vision of the Virgin Mary that the Franciscan brother Bartolomeo d'Ivrea experienced in the night of 14/15 August 1480. The interior is highly decorated, and a platform gives a magnificent view of the city. (Wikipedia)
