For many years, Hanover Square was the center of New York's commodity market, with the New York Cotton Exchange at 1 Hanover Square, on the square's southwest corner; the New York Cocoa Exchange, now the New York Board of Trade; and others nearby. The square was also known as "Printing House Square". The Great Fire of New York broke out here on December 16, 1835, decimating much of Lower Manhattan. 3 Hanover Square, a former home to the New York Cotton Exchange, and 10 Hanover Square, a former office building, were converted to residential use.
