History

Sagno is first mentioned around 1296–99 as Sagnio. Agriculture and livestock constitute the main long-term sources of income. This was supplemented, by a seasonal migration, especially of bricklayers and stonemasons from Italy. Starting in the 1970s, the population increased slightly. In 2000 about four-fifths of the working population of Sagno were commuters, mostly to Chiasso.
