1. Galleria Vittorio Emanuele II
The Galleria Vittorio Emanuele II connects Piazza Duomo to Piazza della Scala through an elegant glass-vaulted arcade that has been Milan's living room since 1877. This is one of the world's oldest shopping malls, though calling it a mall doesn't do it justice - the iron and glass architecture is pure 19th-century ambition, designed to show off what industrial engineering could do when paired with Renaissance-inspired decoration. Locals just call it "la Galleria." Inside, the mosaic floor features symbols of Italian cities, including Turin's bull - stomping on its testicles is supposed to bring good luck, which explains the worn-down spot. High-end shops line both arms of the cross-shaped arcade, but you don't need to buy anything to enjoy it. The real attraction is the space itself and the cafés that have been here for over a century. It's one of the must-see attractions in Milan, not because you need to shop but because it tells you something about the city's relationship with style and public space. Milano built this as a symbol of unity after Italian unification, and it's still where the city comes to see and be seen. Even at midnight, people are here drinking espresso under that vaulted glass ceiling.
