==History== 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.
