Il Duomo di Milano
The construction of Milan’s most famous cathedral started in 1386, and the fabric of the city seems woven into this incredible building, the fifth-largest church in the world. A highlight is the five bronze doors that depict scenes of Milan’s history, and many notable Milanese are buried inside (including one of the architects, Charles Borromeo). The exterior is a panoply of white marble threaded with pink, and the dozens of gothic spires are an icon of the city. Climb up to the roof and walk among some of the thousands of statues, spires, and gargoyles—and take in some of the best views of the city.
