The name comes from ‘oltre senda’, dialect for ‘beyond the path’. In fact, the area stands beyond the road that runs along the Serio valley. The village has two centres, Nasolino and Valzurio. Most of Oltressenda’s territory is on the right bank of the Ogna stream, a tributary of the Serio. Nasolino is the centre, Valzurio is at a higher altitude. Other picturesque little hamlets in the municipality include Dosso, Bricconi, Spinelli, Colle Palazzo, Piazza and Stalle del Moeschel. In the past, the area’s economy was agriculture, forestry and mining for barite and copper. Today it is mainly made up of artisans working in wood and tourism.
