Above we have a circa-1968 SOUTH SHORE PLAZA plan. Sections shown in black, along with the Filene's and Stearns stores, were dedicated between February 1961 and October 1962. A ginormous "Jordan's", and those store blocks shown in gray, were completed in September 1967.
Jordan Marsh's SOUTH SHORE store was the chain's fifth New England branch.
