Cincinnati's Swifton Center  

The Queen City's first mall-type shopping center opened its doors in October 1956. A target trademark was used to promote the original SWIFTON CENTER, which was situated at the geographic center of Greater Cincinnati.

The mall was in planning stages for several years, going under the provisional name of "Woodner Center." A circa-1951 rendering shows an early conception, with the adjacent Swifton Village Apartments seen on the left. The residential complex (but not the shopping center) was once owned by Donald Trump.
