Gibil Gabib (also referred to as Gibil Habib) is an archaeological site located about 5 km south of Caltanissetta, on a 615 metre high mountain. Excavations were first undertaken in the area in the middle of the 19th century and were reprised with great enthusiasm in the 1950s by the archaeologist Dinu Adameșteanu. They came to an end in 1984. In those undertaken in the middle of the 20th century, remains dating to the 6th century BC were brought to light, including parts of the city walls and some ceramic objects of the Bronze Age Castelluccio culture, while the 1980s excavations revealed a defensive tower from the middle of the 6th century BC. This discoveries were of great significance, because they helped to clarify the course of the city wall discovered almost thirty years earlier.
