Olympic Tower, developed by Aristotle Onassis and designed by the architectural firm of Skidmore, Owings & Merrill and completed in 1976, is an important example of the Modernist aesthetic in the city. It introduced major mixed-use towers and glass-curtain walls and reintroduced residential space to midtown Fifth Avenue.The 51-story condominium building contains 225 apartments on its top 29 floors and over 250,000-square feet of office space on floors two through 21 as well as retail space and a through-block public arcade at street level. Views from within the tower's floor-to-ceiling windows are nothing short of dazzling, with its dark bronze-colored fa??ade providing both a contrasting backdrop for views of the St. Patrick's Cathedral from the south as well as reflections of it. Amenities at this full-service luxury residence include a full-time doorman, central air, a fitness center and laundry facilities, and its location puts residents steps from Fifth Avenue shopping, Rockefeller Center and all public transportation.
