What is Chiavenna known for?

Eighty stone cellars built over rock fissures that breathe 7-8 degree air, used as natural fridges across the Valchiavenna. Tenth-century Collegiata with a 1156 pietra ollare font and the Pace di Chiavenna gold evangeliary cover in the treasure museum. Roman and medieval trade route across the central Alps, the position that gave Clavenna, the key, its name.

When is the best time to visit Chiavenna?

May–Oct. May through October is the Alpine season. The Mera trails are open, the Collegiata holds full hours, and the crotti host their summer service of salami, cheese, and Valchiavenna wine. June, July, August and September are the busiest months, with hikers heading up to the Splügen and the Bregaglia valleys. November through April is quiet. Snow falls on the upper passes, the high trails close, and the town belongs to its 7,200 residents and the slow rhythm of the Cittaslow charter. The Sagra dei Crotti in late August and September fills the Pratogiano square with traditional tables.

Chiavenna is a comune in the province of Sondrio, Lombardy region of Italy, about 108 kilometers from Monza.

Why come

Chiavenna is the administrative and cultural centre of the Valchiavenna, at the foot of the Splügen Pass. The town arose on a large ancient landslide, and the boulders that fell across the slope left behind the air pockets and rock crevices that became its defining feature: a crotto is a domed cellar built over one of these cracks, called a sorèl, and Valchiavenna counts about eighty of them, mostly in private hands. The old town sits along the Mera, its stone streets carrying palazzi from the era when the town lived off the trade crossing the Alps, with stretches of foundation going back to Roman work below them.

The church and its font and treasury stand within this same fabric, one more layer laid over the Roman crossroads the town took its name from. The result is a town built twice over by the same geology and the same geography: the rock that cracked open to store food and wine is the same rock the streets and trade route were cut through, so the town's food culture and its position on the pass turn out to be two expressions of one fact of the ground it sits on.
