Famous-Barr, the center's north anchor, opened in October 1973. It would be Famous' fourth -and final- "rotunda store". This design had been used for Greater St. Louis' SOUTH COUNTY, NORTHWEST PLAZA and WEST COUNTY Famous-Barr stores. Meier & Frank (another May Stores subsidiary) also built a rotunda-type store at VALLEY RIVER CENTER, in Eugene, Oregon.
