The Galleria Vittorio Emanuele II is one of the world's oldest shopping malls. Housed within a four-story double arcade in centralMilan, the Galleria is named after Vittorio Emanuele II, the first king of the Kingdom of Italy. It was designed in 1861 and built byGiuseppe Mengoni between 1865 and 1877. The structure consists of two glass-vaulted arcades intersecting in an octagon covering the street connecting Piazza del Duomo to Piazza della Scala. The street is covered by an arching glass and cast iron roof, a popular design for 19th-century arcades, such as the Burlington Arcade in London, which was the prototype for larger glazed shopping arcades.
