"Marvel at Milan’s Duomo The Milan Cathedral, or Duomo, occupies a site that’s been holy since the time of the Romans, but it wasn’t until the early 19th century when the finishing touches were finally placed on this massive building. The Duomo is the fifth largest cathedral in the world and one of the top tourist sites in the northern Italian city. Entrance is free, but a small fee is requested if you wish to take photos. Inside the church is even more magnificent then the outside, with scores of shrines and altars dedicated to saints and notable Milanese. During the Christmas holidays the city’s night market takes up residence next to the cathedral, adding one more reason to visit this central site."
