Misa

The river Misa would be settled by the Senone Gauls in the 4th century BCE after crossing the Alps and Migrating into Italy. Soon after setting up their capital in what would be renamed Senigallia and taking control of the nearby region, the Senones would march into Etruria and Latium, sacking Rome. Centuries later Rome would establish the colony of Sena Gallica on this site.
