The Province of Piacenza is one of Emilia Romagna's provinces, with the city of Piacenza as its capital.

The Po River passes through the province as well as through many medieval villages that lay here: Bobbio, Castell'Arquato, Fiorenzuola d'Arda and so on. Tourists come to visit the province of Piacenza for its many medieval castles as well, for the Romanesque churches and for the peace, quiet and beauty the province is known for.
