1. Ursino Castle, also known as Castello di Ursino, is a medieval fortress located in the city of Catania, Sicily, Italy. It was built between 1239 and 1250 by Frederick II, the Holy Roman Emperor. The castle was originally positioned on the coast but due to volcanic activity, it is now around 1.5 kilometers away from the sea.

The castle has a rectangular shape and consists of four towers at each corner. It was designed to serve as a defensive fortress against invading forces and to control the city of Catania. Over the years, it has withstood earthquakes and volcanic eruptions, serving various purposes from defensive structure to residence for royal families.

Today, Ursino Castle houses the Civic Museum of Catania, which displays artifacts and art collections that reflect the history and culture of the city. The museum showcases archaeological finds, medieval weapons, paintings, sculptures, and other historical items. Visitors can explore the castle’s interior, including the courtyard, towers, and various exhibition halls.
