In the center of Corniglio stands the castle of the thirteenth century that was owned by the Rossi and Farnese and in 1820 was sold to the municipal administration, now the municipal seat. In front of the castle there is the small temple of SS. Lucio and Amanzio dedicated to the fallen. Via Roma is the most characteristic place of Corniglio with carved stone portals, beyond the centuries-old Roman bridge.
