A shopping mall is a modern, chiefly North American, term for a form of shopping precinct or shopping center, in which one or more buildings form a complex of shops representing merchandisers with interconnecting walkways that enable customers to walk from unit to unit. A shopping arcade is a specific form serving the same purpose. Many early shopping arcades such the Burlington Arcade in London, the Galleria Vittorio Emanuele II in Milan and numerous arcades in Paris are famous and still trading.
