Marshall Field and Company Building or Macy`s at State Street is the former flagship location of the former Marshall Field`s department store and the current location of the Chicago flagship of Macy`s. The building is located in the Chicago Loop community area in Cook County, Illinois, United States, and it takes up the entire city block bounded clockwise from the west by North State Street, East Randolph Street, North Wabash Avenue, and East Washington Street. The former department store established numerous important business firsts in this building, and it is regarded as one of the three most influential establishments in the nationwide development of the department store. Both the building name and the name of the stores formerly headquartered at this building changed names on September 9, 2006 as a result of the merger of the May Department Stores (Marshall Field`s former parent) with the Federated Department Stores which led to the integration of the Marshall Field`s stores into the Macy`s retailing network.
