The Half Moon Hotel in Coney Island, Brooklyn, New York, was a 225-foot-tall, 14-story hotel that opened on May 5, 1927, on the Riegelmann Boardwalk at West 29th Street. The Half Moon was built to help Coney Island compete with the beach resort Atlantic City, New Jersey. The hotel was designed by the architectural firm of George B. Post and Sons and built by the Cauldwell-Wingate Co. The name "Half Moon" refers to the name of explorer Henry Hudson's ship, which anchored off Gravesend Bay in Brooklyn (the location of Coney Island), while searching for a short cut to Asia.
