Galleria Umberto I is a public shopping gallery in Naples, southern Italy. It is located directly across from the San Carlo opera house. It was built between 1887–1891, and was the cornerstone in the decades-long rebuilding of Naples — called the risanamento (lit. "making healthy again") — that lasted until World War I. It was designed by Emanuele Rocco, who employed modern architectural elements reminiscent of the Galleria Vittorio Emanuele II in Milan. The Galleria was named for Umberto I, King of Italy at the time of construction.
