One World Trade Center, also known as One World Trade, One WTC, and formerly called the Freedom Tower during initial planning stages, is the main building of the rebuilt World Trade Center complex in Lower Manhattan, New York City. Designed by David Childs of Skidmore, Owings & Merrill, One World Trade Center is the tallest building in the United States, the tallest building in the Western Hemisphere, and the seventh-tallest in the world. The supertall structure has the same name as the North Tower of the original World Trade Center, which was destroyed in the terrorist attacks of September 11, 2001. The new skyscraper stands on the northwest corner of the 16-acre (6.5 ha) World Trade Center site, on the site of the original 6 World Trade Center. It is bounded by West Street to the west, Vesey Street to the north, Fulton Street to the south, and Washington Street to the east.

Lower Manhattan, also known as Downtown Manhattan or Downtown New York, is the southernmost part of Manhattan, the central borough of New York City. The neighborhood is the historical birthplace of New York City and for its first 225 years was the entirety of the city. Lower Manhattan serves as the seat of government of both Manhattan and the entire City of New York. Because there are no municipally defined boundaries for the neighborhood, a precise population cannot be quoted, but several sources have suggested that it was one of the fastest-growing locations in New York City between 2010 and 2020, related to the influx of young adults and significant development of new housing units.
