What significant event took place at Federal Hall?

Federal Hall is historically significant as the site of George Washington's inauguration as the first President of the United States in 1789. This event marked a pivotal moment in American history as it represented the establishment of the nation's executive leadership and the transition from British rule to a new democratic government.

During the inauguration ceremony, Washington took the oath of office on April 30, 1789, a key moment that solidified his role in the fledgling government and set precedents for future presidents. Federal Hall served not just as a physical location for the inauguration, but it also became a symbol of the United States' commitment to democracy and governance by the people.

The other events mentioned, while historically relevant, did not occur at Federal Hall. The Declaration of Independence was signed in Philadelphia, the United Nations was founded in New York City but at a different location, and the Stock Exchange opened in various locations before settling on Wall Street. Therefore, the inauguration at Federal Hall stands out as the defining event associated with this landmark.
