Castel San Giovanni

Castel San Giovanni (Piacentino: ) is a town and "comune" in the province of Piacenza, Emilia-Romagna, Italy.
History.
The origins of the town are probably related to an ancient "pieve" called "Olubra" and a fortress called "Castellus Milonus", which preceded the construction of a new castle by Alberto Scoto in 1290 (now also disappeared).
After a period under the Dal Verme family of lords-condottieri, it became part of the Duchy of Parma and Piacenza in 1485.
