Castello Sforzesco (English: Sforza Castle) is a castle in Milan, Italy that now houses an art gallery. Original construction on the site began in the 14th century. In 1450, Francesco Sforza began reconstruction of the castle, and it was further modified by later generations. It currently houses an art collection which includes Michelangelo's last sculpture, the Rondanini Pietà, and Leonardo da Vinci's Codex Trivulzianus manuscript.

Though it's been clumsily restored many times, most recently at the end of the 19th century, this fortresslike castle continues to evoke Milan's two most powerful medieval and Renaissance families, the Visconti and the Sforza. The Visconti built the castle in the 14th century and the Sforza, who married into the Visconti clan and eclipsed them in power, reconstructed it in 1450. The most influential residents were Ludovico il Moro and Beatrice d'Este (he of the Sforza and she of the famous Este family of Ferrara).

After ill-advisedly calling the French into Italy at the end of the 15th century, Ludovico died in the dungeons of a château in the Loire valley -- but not before the couple made the Castello and Milan one of Italy's great centers of the Renaissance. It was they who commissioned the works by Bramante and Leonardo da Vinci, and these splendors can be viewed on a stroll through the miles of salons that surround the Castello's enormous courtyard.

The salons house a series of small city-administered museums known collectively as the Civici Musei Castello Sforzesco. They include a pinacoteca with works by Bellini, Correggio, and Magenta, and the extensive holdings of the Museo d'Arte Antica, filled with Egyptian funerary objects, prehistoric finds from Lombardy, and the last work of 89-year-old Michelangelo, his unfinished Rondanini Pietà.
