Galleria Vittorio Emanuele II is a covered double arcade (two arcades intersecting in an octagon) sited on the northern side of the Piazza del Duomo in Milan, connecting to the Piazza della Scala. Named after Vittorio Emanuele II, the first king of united Italy, it was originally designed in 1861 and built by Giuseppe Mengoni between 1865 and 1877.
The street is covered over by an arching glass and steel roof, a popular design for nineteenth-century shopping malls (e.g., the Passazh in St Petersburg, opened in 1848). The central point is topped with a glass dome. The Milanese Galleria was larger in scale than its predecessors and was an important step in the evolution of the modern shopping mall. It has inspired the use of the term galleria for many other shopping arcades and malls.
The Galleria connects two of Milan's most famous landmarks: The Duomo and the Teatro Alla Scala.
