The Dauphin Hotel was an establishment located on the west block front of Broadway between 66th Street and 67th Street. In 1958 the ballroom of the hotel was behind Julia Murphy’s Bar. The Dauphin Hotel was demolished as part of the excavation for the Lincoln Center for the Performing Arts. By 1964, the site was taken by the Empire Mutual Insurance Group building. This edifice also occupied the space where the Marie Antoinette Hotel previously stood. – Wikipedia
