Geophysical investigation at "Castle of Canossa"

Canossa Castle is located in a commune of Canossa 18 km (11 mi) South of Reggio Emilia, Reggio Emilia province of Italy. Canossa Castle was constructed in 940 by Adalberto Atto, son of Sigifredo of Lucca. Lombard chieftains needed this strategic hill to defend their lands against intrusions of other barbarian tribes. Subsequent improvements made the stronghold one of the best defended castles in the country. Canossa Castle became particularly famous as a site of reconciliation between king Henry IV and Roman pope Gregory VII during Investiture Controversy in 1077. In order to planned excavations in the area close to the Castle geophysical surveys were undertaken in the spring of 2022. In this paper, the interesting results will be presented.
