An ancient town of Marche, it was known as Fanum Fortunae after a temple of Fortuna located there. Its first mention in history dates from 49 BC, when Julius Caesar held it, along with Pisaurum and Ancona. Caesar Augustus established a colonia, and built a wall, some parts of which remain. In 2 AD Augustus also built an arch (which is still standing) at the entrance to the town.
