Evidence of habitation on the Colfiorito plateau, straddling today's border between Umbria and the Marche, reaches back to the Paleolithic, but Plestia became a real town only when the Umbrian Plestini people settled it permanently around the tenth or ninth century BC.
The Social War of 90 BC brought Roman citizenship and urbanization, turning Plestia into a municipium of the Augustan sixth region, with public buildings and mosaic-floored houses that excavation has since uncovered near the church of Santa Maria di Pistia. The settlement persisted through the Lombard period as a diocese before fading entirely from the historical record after 996 AD, its site and name essentially forgotten until archaeology brought it back. Finds from the excavations, including wealthy Roman domestic mosaics, are held at the nearby Colfiorito Park museum rather than displayed on-site.
