The Rocca Tiepolo is the main symbol of the medieval past of Porto San Giorgio, testifying to the ancient strategic importance of this area and its close link with the nearby city of Fermo. Built on one of the highest points of the settlement, the fortification served as a crucial stronghold for monitoring and defending the territory, protecting the port from constant threats from pirates and incursions by Saracens.
Its construction dates back to 1267 at the behest of the Venetian Lorenzo Tiepolo, then podestà of Fermo, from which the Rocca takes its name. Over the centuries, the complex has come under the control of various figures linked to local history, undergoing modifications and additions that have shaped its current appearance.
The fortification extends over an area of about 1000 square meters and features an irregular pentagonal layout. Its perimeter is marked by five towers connected by a powerful defensive wall, which surrounds the massive central keep, the last defensive bastion and main observation point towards the sea. Today, this historically rich place has changed its function: its ancient walls often host evocative cultural events, transforming the old fortress into an exceptional stage for concerts and theatrical performances.
