One World Trade Center, formerly the Freedom Tower, is the primary building of the new World Trade Center complex in New York City's Lower Manhattan and is the tallest building in the United States.

The building is bordered to the west by West Street, to the north by Vesey Street, to the south by Fulton Street, and to the east by Washington Street.
Construction on below-ground utility relocations, footings, and foundations for the building began on 27 April, 2006. On 30 March, 2009, the Port Authority of New York and New Jersey confirmed that the building would be known by its legal name, One World Trade Center, rather than the colloquial name, Freedom Tower.

Its spire reaches a symbolic height of 1,776ft (541m) in reference to the year of the United States Declaration of Independence.
