Galleria Umberto I is a cool shopping spot in Naples, Italy, right across from the San Carlo opera house. Built in the late 1800s, it's got a fancy glass dome and a cross-shaped layout with shops, cafes, and apartments. Designed by Emanuele Rocco, it's like the Milan Galleria Vittorio Emanuele II's little sibling. After some rough patches, it's back to being a bustling hub of Neapolitan life. Plus, it's part of the UNESCO World Heritage Site in Naples. So, if you're ever in the area, swing by for some shopping and sightseeing!
