In the southern Risorgimento, Centro and Santa Maria Apparente districts, the city lies on the Chienti river floodplain, formed in the Holocene.

Civitanova was founded probably around the 8th century BC as Cluana by the Piceni Italic tribe, at the mouth of the Chienti river.

The Romans captured it in 268 BC, and, in 50 AD, founded a new settlement, Cluentis Vicus (the current frazione of Civitanova Alta) on a hill near the sea.
