La Galleria Umberto I

 This architectural gem was constructed under the reign of King Umberto I by architect Emanuele Rocco. It is similar to the  Galleria Vittorio Emanuele II in Milan. The Umberto I Galleria is near the San Carlo Theater, the oldest opera house in the world while the Vittorio Emanuele II is very close to La Scala and is more famous. Both are great places to have an espresso but the espresso is much better in Naples.
