Galleria Umberto I is a public shopping gallery in Naples, southern Italy.

It was meant to combine businesses, shops, cafés and social life—public space—with private space in the apartments on the third floor.

[1][2] The Galleria is a high and spacious cross-shaped structure, surmounted by a glass dome braced by 16 metal ribs.

Of the four iron and glass-vaulted wings, one fronts on via Toledo (via Roma), still the main downtown thoroughfare, and another opens onto the San Carlo Theatre.

[1][2] The building is part of the UNESCO listing of the Historic Centre of Naples as a World Heritage Site.
