The Siculi town of Halaesa was founded in the 5C BC by the Greeks and the Romans, then later destroyed by the Arabs. Here, archaeologists have unearthed a Roman forum with its sacelli (chapels), a patrician house and several bastions from the Greek-era perimeter wall. It is believed that a temple used to stand on top of the hill (inaccessible to visitors) opposite these bastions, above the River Tusa.
