In the province of Fermo, situated on the border with the territory of its provincial capital, to which it is connected by the via Pompeiana, Porto San Giorgio is a town located on the Adriatic coast, not far from the Sibillini mountain range. It is a seaside resort, famous for its mild climate that attracts tourists all year round. Rich in culture, the town homes various exhibitions of art, literature and music, and also retains a rich culinary tradition.
The town developed as the port area of the nearby city of Fermo and traded with Venice. Under the protection of this neighboring city, with whom it had a symbiotic relationship, except for some episodes of short conflict, it was known as "Portus Firmi" till the Middle Ages. In the XI century, the centre assumed the name of Castel San Giorgio. In the second half of the next century the town was incorporated into the Capitolo (county) of Fermo and was fortified with the construction of fortified walls, to defend it against the Turkish invasions. In the second half of the XIV century the walls were strengthened by order of Giovanni Visconti. In the XVII century, Porto San Giorgio experienced a period of great development, until in 1749 it was invaded by Spanish and German troops. During the Napoleonic domination, the center was detached from Fermo and experienced a certain autonomy. Later the town was assigned to the Papal States until the Unification of Italy.
