Cittadella
The Citadel was built in 1590 at the behest of the Gonzaga to defend the town of Casale Monferrato from various Spanish attacks and from the Savoy Kingdom. It was often the scene of various attacks over the years. Today, only the so-called 'powder' remains, since the original structure was dismembered to leave room for the construction of the city.
