55 Wall Street, formerly the National City Bank Building, is an eight-story building on Wall Street between William and Hanover streets in the Financial District of Lower Manhattan in New York City, New York, United States. The lowest three stories were completed in either 1841 or 1842 as the four-story Merchants' Exchange and designed by Isaiah Rogers in the Greek Revival style. Between 1907 and 1910, McKim, Mead & White removed the original fourth story and added five floors to create the present building. Since 2006, the banking room has functioned as an event venue called the Cipriani Wall Street, while the upper stories have been a condominium development known as the Cipriani Club Residences.
