2. Visit the Duomo
One of the biggest gothic Cathedrals in the world, the Duomo is one of the best places to visit in Milan. The building stretches for 320+ in width and 520+ feet in length and the tallest spire is over 300 feet high. Façades are covered by lush Gothic ornaments. Be sure to take a walk through the forest of spires and statues on the cathedral roof.
