Vassallaggi is a Sicilian prehistoric bronze age archaeological site, located on the hill of the same name, which had a later flourishing after the 7th century BC as a phrourion (fortress). The site is located in the middle of the Salso river valley, at 704 m above sea level, near San Cataldo in the province of Caltanissetta, in a strategic location for communication between the southern coast of Sicily and the northern part of the island. It has a NE-SW orientation and stretches along in parallel with the SS 122 San Cataldo- Serradifalco.
This archaeological site developed over time on five small hills in close proximity to one another. It represents an important example of a Greek settlement in central Sicily, having apparently taken on increasing amounts of Greek cultural forms as a result of Greek people arriving from Rhodes and Crete, via Akragas. The site's position is critical for controlling the central Salso river valley.
The site, known already in the 19th century, only became the subject of excavation from 1905. These excavations continued until the 1960s and produced brilliant results, including the discovery of considerable evidence for human habitation from the Bronze Age until the first centuries CE. Remains of walls, houses, streets, tombs and religious sites provide evidence of a prosperous community. Numerous items, some perfectly preserved, are now on display in various museums throughout Sicily.
