Town in the province of Bologna, situated near the basin fields of the river Lavino, the area of Monte San Pietro has been inhabited since 2500 B.C., as revealed by the finds from the Bronze Age found in San Martino of Casola. Evident are the remains of the Iron Age, the periods of the Villanova, of the Etruscans and of the subsequent domination of the Gauls. After the fall of the Roman Empire in 568 it became part of the Lombard kingdom. For the particular geographic conformation of the territory, characterized by hills and mountains, the area became building site of several castles and fortresses with the purpose to dominate the strategic control of the area. The inhabitants were involved in secular disputes between Bologna and Modena, and the town was ruled by several local nobles, such as the Accounts of Panico, of dell'Amola and Cattani and the Vassals of Matilda of Canossa .
