According to the archeologist Italo Biddittu, human presence is evidenced during the Copper Age, whilst a settlement arose in the Iron Age.
The Volsci built a fortress around the mountain, still partially visible today. Due to its strategic position, the fortress had a moderate importance in the medieval period.
