shopping mall was opened in Luleå, in northern Sweden (architect: Ralph Erskine) and was named Shopping; the region now claims the highest shopping center density in Europe. The idea of a regionally-sized, fully enclosed shopping complex was pioneered in 1956 by the Austrian-born architect and American immigrant Victor Gruen. This new generation of regional-size shopping centers began with the Gruen-designed Southdale Center, which opened in the Twin Cities suburb of Edina, Minnesota, United States in October 1956. For pioneering the soon-to-be enormously popular mall concept in this form, Gruen has been called the "most influential architect of the twentieth century" by Malcolm Gladwell. The first retail complex to be promoted as a "mall" was Paramus, New Jersey's Bergen Mall. The center, which opened with an open-air format in 1957, was enclosed in 1973. Aside from Southdale Center, significant early enclosed shopping malls were Harundale Mall (1958) in Glen Burnie, Maryland, Big Town Mall (1959) in Mesquite, Texas, Chris-Town Mall (1961) in Phoenix, Arizona, and Randhurst Center (1962) in Mount Prospect, Illinois. Other early malls moved retailing away from the dense, commercial downtowns into the largely residential suburbs. This formula (enclosed space with stores attached, away from downtown, and accessible only by automobile) became a popular way to build retail across the world. Gruen himself came to abhor this effect of his new design; he decried the creation of enormous "land wasting seas of parking" and the spread of suburban sprawl. Decline of the mall Since the 1990s, the shopping mall has been in decline because of competition from discount stores and other shopping center formats, from e-commerce and most recently from closures and economic effects of the COVID-19 pandemic. History of shopping centers outside the U.S. Canada Don Mills Convenience Centre (now Shops at Don Mills) opened in 1955, in Toronto, Ontario. The first fully enclosed shopping mall in Canada was Wellington Square. It was designed for Eaton's by John Graham, Jr. as an enclosed mall with a department store anchor and subterranean parking which opened in downtown London, Ontario, on August 11, 1960. After several renovations, it remains open today as Citi Plaza. In the 1970s in Canada, the Ontario government created the Ontario Downtown Renewal Programme, which helped finance the building of several downtown malls across Ontario such as Eaton Centre. The program was created to reverse the tide of small business leaving downtowns for larger sites surrounding
