34 Best Sights in Milan, Italy

Sixteen ancient Roman columns line the front of this sanctuary; remnants of 4th-century Paleo-Christian mosaics survive in the Cappella di Sant'Aquilino (Chapel of St. Aquilinus).

Just a few steps from the Duomo, this architectural gem was first built in 876 and later perfected by Bramante (1444–1514), demonstrating his command of proportion and perspective—hallmarks of Renaissance architecture. Bramante tricks the eye with a famous optical illusion that makes a small interior seem extraordinarily spacious and airy, while accommodating a beloved 13th-century fresco.

It is worth visiting Parco Sempione just to see the Torre Branca. Designed by architect Gio Ponti (1891–1979), who was behind so many of the projects that made Milan the design capital that it is, this steel tower rises 330 feet over the Triennale. Take the elevator to get a nice view of the city, then have a drink at the glitzy Justme Milano restaurant and club at its base.

In addition to honoring Italy's design talent, the Triennale also offers a regular series of exhibitions on design from around the world. A spectacular bridge entrance leads to a permanent collection, an exhibition space, and a stylish café and rooftop restaurant with expansive views. The Triennale also manages the fascinating museum-studio of designer Achille Castiglioni, in nearby Piazza Castello (open only with hour-long prebooked guided tours, available Tuesday through Friday at 10, 11, and noon, and one Saturday a month  €15.
