San Sosti (Calabrian: Neapolitan: Santisuòsti; from) is a comune in the province of Cosenza, in Calabria, southern Italy.
A highly decorated bronze axe-head was discovered near San Sosti in 1846. This votive offering was later bought by the collector and goldsmith Alessandro Castellani, from whom it was eventually acquired by the British Museum in 1884.[2] On the axe is inscribed an important dedication in the Achaean dialect of Ancient Greek that can be dated to the sixth century BC.
In 1448, people from Albania migrated to San Sosti.
