Wall Street features many examples of grand architecture, including the New York Stock Exchange and the 18th-century Federal Hall, commemorating the site where the first US Congress convened and Washington was sworn in as president. More contemporary works include Santiago Calatrava’s World Trade Center Oculus and One World Trade Center, the tallest skyscraper in the Western Hemisphere.
With New York’s Financial District also inextricably connected to the September 11, 2001 terrorist attacks, many walking tours of the area include visits to the National September 11 Memorial. Tours (private and group) typically also take visitors to such landmarks as the Charging Bull sculpture and New York Stock Exchange and some also include access to the One World Observatory. Fans of the hit musical Hamilton can also take a specialized walking tour to places associated with the Founding Father.
