Cosa, the making of a Roman town

the long version

"Cosa was a Latin colonia founded under Roman influence in southwestern Tuscany in 273 BC, perhaps on land confiscated from the Etruscans (Velleius Paterculus 1.14.7; Livy Periochae 14; Strabo 5.2.8). The Etruscan site (called Cusi or Cosia) may have been where modern Orbetello stands; a fortification wall in polygonal masonry at Orbetello's lagoon may be in phase with the walls of Cosa. The position of Cosa is distinct, rising some 113 metres above sea level and is sited 140 km northwest of Rome on the Tyrrhenian Sea coast, on a hill near the small town of Ansedonia. The town experienced a hard life and was never truly a prosperous Roman city, although it has assumed a position of prominence in Roman archaeology owing to the circumstances of its excavation."--Wikipedia.
