The area of Lavello was settled in prehistoric times, as attested by findings of an Iron Age village. The town originated as a Daunian and then Roman settlement, known as Forentum.[4] It was an important stronghold during the Lombard rule in southern Italy, and here was killed Sicard of Benevento (839).
Lavello was an important Byzantine center and a bishopric seat from 1025. Starting from 1043 Lavello was one of the twelve baronies of the Normancounty of Apulia in southern Italy. The Normans rebuilt the cathedral and added a line of walls.[4] The fortress was strengthened under their successors, the Hohenstaufen. Here King Conrad IV of Germany died in 1254. As a result of its participation in the anti-Angevine revolt in 1268, it was burnt down by Charles I of Anjou in 1298. The castle has since been transformed into the town hall.[4]
The Church of Annunziata, which is in Lavello, was built during the Norman age and dedicated to the Blessed Virgin Assumption. A limestone sarcophagus from 1550 is situated in the chapel along with altarpieces and wooden statues. Renovations of the church have occurred since the sixteenth century and have continued into the 20th century; in 1986, the central nave floor was redone.[4]
