Felsina, city founded by Etruscans about 510 bce on the site of modern Bologna, Italy, an area rich in Villanovan Iron Age remains. By the mid-4th century Felsina had fallen to invading Gauls (Boii tribe), who called it Bononia. The city was captured by Rome in 196 bce and was colonized seven years later.
Before Etruscan times the Bologna area was an important center of Villanovan Iron Age cultures of the central European Urnfield type that dominated northern and west-central Italy from the Po River to northern Campania and that in Tuscany and Latium provided the ethnic substratum of Etruscan culture. The site of Villanova is 5 miles (about 8 km) northwest of Bologna, and the information found in the cemeteries west of Bologna provides the basis for dating all Villanovan material culture. Works are divided into three phases: Benacci I (c. 1050–900 bce), Benacci II (c. 900–700 bce), and Arnoaldi (c. 700–450 bce). The last phase overlaps but is culturally distinct from the Etruscan period, to which belong the graves at Certosa, a monastery a mile (1.6 km) from Bologna.
