The Rio Shopping Center was a 120,000-square-foot (11,000 m2) open-air shopping center in Atlanta. It was located at the southeast corner of Piedmont Avenue and North Avenue in the northwesternmost part of what is now the Old Fourth Ward, at its border of SoNo and Midtown Atlanta. It was designed by Arquitectonica in postmodern style, landscaped by Martha Schwartz and opened in the Fall of 1988. It was the first free-standing complex of its kind to be built in central Atlanta in more than twenty years.
