The Castello Sforzesco, held by the Visconti and the Sforza families who ruled Milan from 1277 to 1447 and from 1450 to 1535 respectively, was built in 1368 and rebuilt in 1450. The 70-meter Torre de Filarete is a 1905 reproduction of the original gate-tower.
The Castello houses the Musei del Castello Sforzesco, a series of museums, one of which features sculpture. The collection includes the Pietà Rondanini, Michelangelo’s last masterpiece, brought here in 1953 from the Palazzo Rondanini in Rome.
Other museums feature a collection of decorative art, prehistoric and Egyptian antiquities, a collection of musical history, and an armory of weapons and medieval armor.
The picture gallery includes paintings by Bellini, Correggio, Mantegna, Bergognone, Foppa, Lotto, Tintoretto, and Antonello da Messina. Between the two rear courtyards of the Castello, a passage leads into the park, originally the garden of the dukes of Milan and later a military training ground.
