Milan's late-19th-century version of a mall is this wonderful steel-and-glass-covered, cross-shaped arcade. The elegant Galleria is the prototype of the enclosed shopping malls that were to become the hallmark of 20th-century consumerism. It's safe to say that none of the imitators have come close to matching the Galleria for style and flair. The designer of this urban marvel, Giuseppe Mengoni, didn't live to see the Milanese embrace his creation: He tripped and fell from a girder a few days before the Galleria opened in 1878. His shopping mall par excellence provides a lovely route between the Duomo and La Scala and is a fine locale for watching the flocks of well-dressed Milanese -- you'll understand why the Galleria is called Il Salotto di Milano (the drawing room of Milan).
