In the early 1960s, shopping mall exterior design was morphing toward a Moorish Modern motif. The accompanying interior decor style was known as Mediterranean. There were lots of arches. By the mid-1960s, many public buildings were featuring shake-shingled Mansard rooflines, as well.
The early '60s-to-early '70s Moorish-influenced style, demonstrated by the circa-1971 Marshall Field & Company at Chicagoland's WOODFIELD MALL. Below this is an example of one of the many mansard-roofed structures built in the years between 1965 and 1975.
By the dawn of the 1970s, a new movement was well underway in the design and construction of shopping malls and their associated buildings. Referred to today as '70s Brutalist, the style had had its beginnings as far back as the mid-1950s. Exteriors were stark, concrete caisson-like hulks, with few windows.
Two examples of '70s Brutalist style. First, we have the circa-1972 Pogue's at Greater Cincinnati's NORTHGATE MALL. Next in line is the circa-1971 Joske's at Austin's HIGHLAND MALL.
