Castel San Pietro Romano is an Italian municipality with about 4,500 inhabitants located in the Lazio region, in the province of Rome. The city has a long history dating back to the Roman era, as evidenced by the numerous ruins and archaeological remains that can still be found in the area. During the medieval period, Castel San Pietro Romano was an important agricultural and industrial center, and later became a fortified city due to its strategic position on a hill. The name of the city derives from the castle built in the 9th century by the Frangipane family.


During the Middle Ages, the castle was a reference point for the defense of the area, and during the following centuries it was used as a residence for the representatives of the popes and cardinals.
Over the centuries, the city has experienced a series of important historical events, including the wars between the papacy and the Empire, the struggle for control of Lazio between local noble families, and barbarian invasions. Despite these difficulties, the city has managed to maintain its importance as an economic and cultural center.
Today, the city is a highly appreciated tourist destination for its scenic beauty, the presence of archaeological remains, and its important historical and cultural heritage, represented by its historic center, where churches, palaces, and medieval streets can be admired.
