Originally the Merchants' Exchange, and later the United States Customs House, the building's interior was modified and floors were added for First National City Bank. The full-block three-story Greek Ionic granite base with a Roman banking hall, and three superimposed stories with Corinthian columns currently houses the Regent Hotel. A remarkable example of the adaptability and durability of Romantic Classical planning and design, the building is included in the National Register of Historic Landmarks, The U.S. and New York State Registers of Historic Places, and the Landmark Preservation Committee list for both its interiors and exterior.
