The Fortezza di Montalcino is the town's muscular landmark, a 14th-century fortress built into the upper edge of the hill. Its walls frame wide views over vineyards, Val d'Orcia, and the darker bulk of Monte Amiata in the distance.
Inside, the mood is more wine than war these days, but the structure still has real presence. Climb the walls if access is open, then linger in the courtyard or nearby enoteca before dropping back into the town lanes.
