The Marquis Theatre is a Broadway theatre located at 46th Street Between Broadway and Eighth Avenue in midtown-Manhattan. Situated on the third floor of the Marriott Marquis Hotel, the 1611-seat venue was designed by developer/architect John C. Portman, Jr. Because construction of the hotel involved the demolition of five theaters – the original Helen Hayes, the Morosco, the Bijou, and remnants of the Astor and the Gaiety – New York City officials permitted Portman to construct the new property only if he agreed to include a theater within the structure. It presently is one of nine operated by the Nederlander Organization.
