The New York Stock Exchange, a name adopted in 1863, was originally established by a group of 24 stockbrokers in 1792, outside of 68 Wall Street. In 1903, the NYSE moved into this neoclassical building with a much larger trading floor, with paneled Georgian marble walls, huge windows and a gilded ceiling, four stories above ground. The trading posts, dotted through the center of the room began as simple signposts and expanded over time.

After the First World War, the NYSE needed another expansion, so the Board acquired parcels to the north at the intersection of Broad and Wall Street and commissioned the firm of Trowbridge and Livingston to design the 11 Wall Street Annex. Construction started in 1920 and the building was completed in 1922.
