Casaprota is located along the Via Salaria, the road that brought the salt from Sabina, northeast of Rome.
In this area there were many Roman villas and people who lived in the valley until the arrival of the Barbarian invasions. Around the tenth century, the population sought refuge on the heights in a fortified castle (castrum) under the control of the Abbey of Farfa.
At the end of the XIV century, the fiefdom was assigned to the Soderini family, then passed under the Orsini family until 1641 when the Gentili and Vincenti families followed.
The name is a compound of the word “home” and presumably of a person’s name, whose origin is unclear.
