Milan Duomo

First off, it took over 600 years to complete this awe-inspiring cathedral, with construction beginning in 1386 and officially ending in 1965. That's a labor of love, my friends. Second, the cathedral boasts an impressive collection of over 3,400 statues, including the famous golden Madonna statue perched atop the highest spire. And here's a fun fact for you: Legend has it that if you spin around three times on one of the floor's mosaic bulls, you'll bring good luck and ensure your return to Milan. So, don't forget to give it a whirl!
