Cosa was a Latin colony founded by Rome in 273 BC in a territory confiscated from the Etruscan city of Vulci. The town became an agricultural and commercial centre, whose trade can be traced in part through a distinctive type of amphora to destinations throughout the Mediterrnean world. But Cosa's archaeological importance lies in the information its structure and town-planning provide about the Republican period.
