The new city began to expand after the Sicilian Greeks from Syracuse had defeated the Etruscans at the Battle of Cumae in 474 BC, the Etruscans' southern expansion was stopped and Greek domination of the gulf re-established. The new city did not replace the "Old City" but probably expanded mainly its commercial activity. The original centre of Parthenope on the hill of Pizzofalcone came to be called simply "Palaipolis" (Latin: "Palaepolis"), the "old city", but remained the administrative centre.
