New York Stock Exchange
Why it's listed
Two linked marble buildings at 18 Broad Street and 11 Wall Street in Lower Manhattan form the historic core of the New York Stock Exchange. The 10-story Broad Street building, finished in 1903, was designed by George B. Post in the Neo-Classical style. Its facade has six tall Corinthian columns and a pediment with marble figures by John Q. A. Ward, which were replaced in 1936 with copper copies after weathering. The adjoining 23-story building at 11 Wall Street, designed by Trowbridge and Livingston and completed in 1922, was made to complement the older structure, with balustrades and belt courses joining the two facades. Inside, the trading floor and the Governors' Room in the older building have changed little. The Exchange began in 1792, moved among many locations, and has occupied part of this site since 1865. The nomination presents it as the country's principal securities market and a central institution in American economic life.
Significance in brief: The nomination argues that the Exchange has played a central role in American economic development for more than 175 years and became the nation's principal securities market early in the 19th century. The Exchange has occupied part of this site since 1865 and the 18 Broad Street building since 1903. The two nominated buildings are the historic core of the complex, and the 18 Broad Street building is largely free of major structural alteration.
