Sforza Castle (Castello Sforzesco) is an imposing medieval fortress located in Milan, Italy, originally built in the 15th century by Francesco Sforza, Duke of Milan. The castle has a rich history, having undergone several transformations and restorations over the centuries. Once a symbol of the power and authority of the ruling Sforza family, it later served various functions, including a military barracks, a private residence for the Habsburg rulers, and finally as a major cultural center after being significantly damaged during World War II. Today, Sforza Castle houses several of Milan's most important museums and art collections, including the Museum of Ancient Art, the Egyptian Museum, the Museum of Musical Instruments, and the Pinacoteca del Castello Sforzesco with a broad variety of sculptures and paintings. The castle's architecture features robust walls, massive towers, and a large courtyard, the Piazza d'Armi, which hosts various public events. Art and history enthusiasts can admire the frescoes by Leonardo da Vinci and Bramante, who worked in the castle, and the Rondanini Pietà , Michelangelo's last sculpture.
