The ancient Roman colony of Forum Sempronii took its name from Gaius Sempronius Gracchus.
Fossombrone was included in the Donation of Pepin, but remained subject to the Duchy of Spoleto until 1198, when it passed under Papal rule. The Malatesta sold it to the famous Federico III da Montefeltro, under whom the city flourished. Also positive for the city was the reign of the della Rovere dukes, who enlarged it (in particular, Francesco Maria II expanded the settlement in the lower area up to the Metauro river). In 1631 it returned to the Papal States, and was annexed to Italy in 1860.
The city and its environs abound in antiquities, especially inscriptions. Noteworthy remains are the statue of the god Vertumnus; the Furlo Pass, constructed by the Emperor Vespasian to shorten the passage of that mountain; the bridge of Trajan (115) near Calmazzo, and the bridge now called Ponte della Concordia, originally built in 292 by Diocletian, both over the Metaurus.
