Macy's Herald Square (originally named the R. H. Macy and Company Store) is the flagship of Macy's department store, as well as the Macy's, Inc. corporate headquarters, on Herald Square in Manhattan, New York City. The building's 2.5 million square feet (230,000 m2), which includes 1.25 million square feet (116,000 m2) of retail space, makes it the largest department store in the United States and among the largest in the world. The Macy's building was completed in 1902 after the store had occupied several previous locations in New York City. The building was added to the National Register of Historic Places and was made a National Historic Landmark in 1978. From Wikipedia
