The New York Stock Exchange stands as a historic landmark, deeply intertwined with significant events in world history. Notably, it was at the center of the Black Thursday crash on October 24, 1929. This incident, along with the panic-induced sell-off that began on Black Tuesday, October 29, marked the onset of the Great Depression, a global economic crisis that defined the early 1930s.
The present Exchange building, which opened its doors in 1903, is an architectural masterpiece. Its design is highlighted by six massive Corinthian columns that stretch across its Broad Street facade. These columns lend the building an air of substance and stability, symbolizing America's growth and prosperity to many who gaze upon it.
Since the events of September 11, 2001, the New York Stock Exchange building has been closed to the public. This measure was taken to ensure security and safety, making it a site now only accessible to those within the financial industry. Despite this, its historical and architectural significance continues to capture the imagination of many.
