What was South Dakota's first mall? Some may cite Aberdeen's SUPER CITY CENTER, which opened in April 1964. It was a fully-enclosed facility, but encompassed only 138,000 square feet. Moreover, it didn't have an anchor store. The first regional-class mall in South Dakota would have been Sioux Falls' WESTERN MALL, which was dedicated in October 1968.

The mall in Sioux Falls was 10 years old by the time of this site plan. The original complex had been expanded with a second cinematic auditorium in 1974 (in gray). By 1978, WESTERN MALL housed around fifty-two stores and services and spanned approximately 400,000 leasable square feet.
