Casnigo

Casnigo is at an altitude of 514 metres on a high plain that dominates a long tract of the left bank of the River Serio at about 23 kilometres from Bergamo. Even today, the villagers call this plateau Agher, from ager, the Latin word for field, country, and is an alluvial deposit that was intensely cultivated in the past for its fertility, but today is partly occupied by the chemical and textile industries. The Colle Bondo hamlet, which is on the other side of the valley at between 800 and 1,100 metres, still maintains its mainly agricultural traditions today. The main hamlet of Serio, which hosts important factories, is on the valley floor on the bank of the river of the same name at an altitude of around 400 metres.
