Municipality in the province of Ancona, located halfway between the gorge della Rossa and the Adriatic sea, on a hill on the left bank of the Esino, Jesi is surrounded by several smaller towns, known as the castles of Jesi, universally known for the production of a famous Verdicchio wine. The town center is extremely well connected since Roman times and this efficient communication network, contributed enormously to its development.
The first settlement was probably founded by the Umbrians, followed in the IV century B.C. by the Gauls during their expansion, the area became an important crossroad of different peoples and civilizations. In 247 B.C. the Romans created their own colony and when the Empire fell, the city was spared from the destruction inflicted to the nearby towns by the Goths and the Lombards. Around year 1000, the city was ceded by Otto III to Pope Sylvester II: the bishop's possessions were added to those several feudal lords of the area, including those of the Earls of Jesi. In the XII century, when Jesi was proclaimed municipality, the city submitted a period of crisis of the feudal power. Tied to the Ghibellines, the end of the XIII century, the city witnessed a significant demographic and urban expansion with the formation of three districts. Between the XIV and XV centuries it was involved in the struggles between Guelphs and Ghibellines. Later the city was incorporated in the domain of the papal vicar, while later it was ruled by the Sforza. The XV century was highlighted by clashes with the nearby cities of Fabriano and Ancona, epidemics of plague and continuous raids, until the middle of the same century, when it returned under the ecclesiastical control, which permitted a period of economic growth that lasted up to the XVIII century. Around the mid-XIX century, Jesi submitted a new urban expansion and after the First World War it consolidated its role as an industrial city.
