Fusio is first mentioned in 1258 as Fuxio.
The population reached its peak in the 16th-17th Century (400-500 inhabitants), but towards the end of the 18th Century began a slow decline. This slow decline accelerated dramatically after 1950 because of emigration to the cities. Most of the remaining population is elderly.
The local economy relied on livestock, pastures and forestry. The village possessed vast pastures and alpine pastures, which explains the relatively small number of emigrants overseas. Until the second half of the 19th Century there were two mines in the village that produced steatite (soapstone). Through the construction of the dam in the Sambuco valley (1950–56) the amount of agricultural land has been reduced. From the 1980s a number of houses and an inn were built.
The hamlet of Mogno was also part of the village. In the 17th Century it possessed 50 taxable fireplaces. By 1801, the population had dropped to just 40 inhabitants. Today it is no longer inhabited all year round and serves only as a holiday village. Before Mogno was incorporated in 1936 into Fusio it was part of Peccia, and the land around the settlement was shared between Fusio, Peccia, Prato and Sornica.
The church of San Giovanni Battista Decollato was built in 1626 and was initially a chapel of ease of the parish of Peccia. Towards the end of the 17th Century it became an independent parish church. In 1940 it became part of the parish of Fusio. The church was destroyed in 1986 by an avalanche. The new building, by Mario Botta, was built in 1997 after 10 years of planning and construction work. The unique construction of the building has already become a point of interest and a source of critical debate.
