Sforza Castle (Italian: Castello Sforzesco) is in Milan, northern Italy. It was built in the 15th century by Francesco Sforza, Duke of Milan, on the remains of a 14th-century fortification. Later renovated and enlarged, in the 16th and 17th centuries it was one of the largest citadels in Europe. Extensively rebuilt by Luca Beltrami in 1891–1905, it now houses several of the city's museums and art collections.

The original construction was ordered by local lord Galeazzo II Visconti in 1358–c. 1370; this castle was known as Castello di Porta Giova (or Porta Zubia), from the name of a gate in walls located nearby. His successors Gian Galeazzo, Giovanni Maria and Filippo Maria Visconti enlarged it, until it became a square-plan castle with 200 m-long sides, four towers at the corners and up to 7-metre-thick (23 ft) walls. The castle was the main residence in the city of its Visconti lords, and was destroyed by the short-lived Golden Ambrosian Republic which ousted them in 1447.

In 1450, Francesco Sforza, once he shattered the republicans, began reconstruction of the castle to turn it into his princely residence. In 1452 he hired sculptor and architect Filarete to design and decorate the central tower, which is still known as Torre del Filarete. After Francesco's death, the construction was continued by his son Galeazzo Maria, under architect Benedetto Ferrini. The decoration was executed by local painters. In 1476, during the regency of Bona of Savoy, the tower with her name was built.

In 1494 Ludovico Sforza became lord of Milan, and called numerous artists to decorate the castle. These include Leonardo da Vinci (who frescoed several rooms, in collaboration with Bernardino Zenale and Bernardino Butinone) and Bramante, who painted frescoes in the Sala del Tesoro; the Sala della Balla was decorated with Francesco Sforza's deeds. Around 1498, Leonardo worked at the ceiling of the Sala delle Asse, painting decorations of vegetable motifs. In the following years, however, the castle was damaged by assaults from Italian, French and German troops; a bastion, known as was added, perhaps designed by Cesare Cesariano. After the French victory in the 1515 Battle of Marignano, the defeated Maximilian Sforza, his Swiss mercenaries, and the cardinal-bishop of Sion retreated into the castle. However, King Francis I of France followed them into Milan, and his sappers placed mines under the castle's foundations, whereupon the defenders capitulated. In 1521, in a period in which it was used as a weapons depot, the Torre del Filarete exploded. When Francesco II Sforza returned briefly to power in Milan, he had the fortress restored and enlarged, and a part of it adapted as residence for his wife, Christina of Denmark.
