Description : Suasa was an ancient Roman town in what is now the comune of Castelleone di Suasa, Marche, Italy. It is located in the Pian Volpello locality, in the valley of the Cesano River. Suasa was founded by the Romans in the early 3rd century BC, after the Battle of Sentinum (295 BC), in a territory inhabited by the Senones. The town was crossed by a secondary branch of the Via Flaminia and by the Via Salaria Gallica, which connected it to Forum Sempronii (Fossombrone) and Ostra. In 232 BC, it became a prefecture and, in the 1st century BC, a municipium. Suasa started to decline from the 3rd century; in 409, it was sacked by Alarich's Goths during his march against Rome (see Sack of Rome). It was abandoned in the 6th century after the Gothic War, the population moving to nearby settlements.
