Beautiful sanctuary! Very well known in the valley. Very popular with the faithful. Worth a visit. The climb from the main road is challenging. About 2 km with an average gradient of about 9% (4-5 hairpin bends).

Mine from which galena (Lead Sulfide) was extracted. It is located 20 minutes from the Alpinisti Monzesi refuge, at the foot of Mount Resegone, where you can observe some entrances to the mine, located on three levels (one collapsed). On the way there are some structures in ruins. Located at 1225 meters above sea level, the mine is also known as "della Rolla".
