The First Federal Hall
After the Revolutionary War, architect and engineer Peter L’Enfant remodeled the City Hall to house the new American government. Renamed Federal Hall, this is where the First Congress convened. George Washington took his Presidential oath of office on the second floor balcony in April, 1789.
Congress left New York in 1790 for Philadelphia and, eventually, moved to Washington D.C. The design of the newly constructed Washington D.C. capitol building evoked classical ideals of democracy. In subsequent decades, many government buildings in the young country were designed in this popular neo-classical style, including the building on Wall Street that we know as Federal Hall today.
