8 Best Sights in Duomo, Milan

There is no denying that for sheer size and complexity, the Duomo is unrivaled in Italy. It is the second-largest church in the country—the largest being St. Peter's in Rome. This intricate Gothic structure has been fascinating and exasperating visitors and conquerors alike since it was begun by Gian Galeazzo Visconti III (1351–1402), first duke of Milan, in 1386. Consecrated in the 15th or 16th century, it was not completed until just before the coronation of Napoléon as king of Italy in 1809.

The building is adorned with 135 marble spires and 2,245 marble statues. The Duomo's most famous sculpture is the gruesome but anatomically instructive figure of San Bartolomeo (St. Bartholomew), who was flayed alive. As you enter the apse to admire those splendid windows, glance at the sacristy doors to the right and left of the altar. The lunette on the right dates from 1393 and was decorated by Hans von Fernach.

This spectacular late-19th-century Belle Époque tunnel is essentially one of the planet's earliest and most select shopping malls, with upscale tenants that include Gucci and Prada. This is the city's heart, midway between the Duomo and La Scala. It teems with life, which makes for great people-watching from the tables that spill out from bars and restaurants, where you can enjoy an overpriced coffee. Books, clothing, food, hats, and jewelry are all for sale. Known as Milan's "parlor," the Galleria is often viewed as a barometer of the city's well-being.

Elaborately decorated with painted ceilings and grand staircases, this former royal palace close to the Duomo is almost worth a visit in itself; however, it also functions as one of Milan's major art galleries, with a focus on modern artists. Exhibitions have highlighted works by Picasso, Chagall, Warhol, Pollock, and Kandinsky. Check the website before you visit to see what's on; purchase tickets online in advance to save time in the queues, which are often long and chaotic.

More specifically known as the Baptistry of San Giovanni alle Fonti, this 4th-century baptistry is one of two that lie beneath the Duomo. Although opinion remains divided, it is widely believed to be where Ambrose, Milan's first bishop and patron saint, baptized Augustine. Tickets also include a visit to the Duomo and its museum.

This contemporary photography and visual languages exhibition space, developed in partnership with Fondazione Prada, is spread over two floors in the Galleria Vittorio Emanuele II. Exhibitions, which rotate several times a year, explore the cultural and social implications of expression. The space itself, bombed after World War II and then fully restored, is worth visiting just for the unique view of the Galleria dome through the large windows. You can reach the gallery via the elevator next to the Prada store.

Ascend a Guggenheim-esque spiral walkway to reach the modern works at this petite yet dense collection of Italian contemporary art, adjacent to the Duomo. The museum highlights 20th-century Italian artists, including a strong showing of Futurists, like Boccioni and Severini, and sculptures from Marini, along with a smattering of works by other European artists, including Picasso, Braque, and Matisse.

Cardinal Federico Borromeo, one of Milan's native saints, founded this picture gallery in 1618 with the addition of his personal art collection to a bequest of books to Italy's first public library. The core works of the collection include such treasures as Caravaggio's Basket of Fruit, Raphael's monumental preparatory drawing (known as a "cartoon") for The School of Athens, which hangs in the Vatican, and Leonardo da Vinci's Portrait of a Musician. The highlight for many is Leonardo's Codex Atlanticus, which features thousands of his sketches and drawings.

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.
