The village extends from the shore of the lake to Monte Preàla. The higher part of the village is called Castello because it was fortified in the Middle Ages. It took part in the feud of Nesso, which was ruled by the Visconti family but was later ceded by the Spanish to the Gallio family. On a mule-track from Pognana up the Colma della Guardia, there is a deep crevice in the rock, called the buco di Premen. The area has many caves that have not been explored yet. The village was once famous for its quarries of Moltrasina stone. This activity has almost disappeared, as has the cultivation of crops.
