Ursino Castle
One of the main sights near Principe di francalanza is Ursino Castle:
it was built by Frederick II, Holy Roman Emperor, in the 13th century. It was an important building during the Sicilian Vespers, as a parliament, and afterwards as the seat of the Aragonese.
Today it is Catania Civic Museum, where you can find the Biscari and Benedettini collections.
