The Olympia Theatre (1514–16 Broadway at 44th Street), also known as Hammerstein's Olympia, was a theatre complex built by impresario Oscar Hammerstein I in Longacre Square (later Times Square), New York City, opening in 1895. It consisted of a theatre, a music hall, a concert hall, and a roof garden. Later, sections of the structure were substantially remodeled and used for both live theatre and for motion pictures.
