Castello Sforzesco and Parco Sempione
Time Out says
Built by Francesco Sforza in the 15th century, this castle was originally a family residence, and quite an imposing one at that. It was in the late 19th and early 20th century that its signature Filarete Tower was added to the façade by Luca Beltrami as part of a partial reconstruction. The halls that once held Napoleon’s troops now constitute the city’s largest exhibition complex. The Museo d’Arte Antica (Ancient Art Museum) is particularly popular, mostly because it occupies the Sala delle Asse, which was decorated by da Vinci. At the back of the castle is Parco Sempione, the largest green space in the city center and where all segments of Milanese society come together for a bit of fresh air.
Time Out tip: To get away from the crowds in the castle, head towards the middle of the park, where you’ll find the X Triennial Pavilion (1954), which has been converted into a public library. It’s the perfect spot to unwind with a book.
