One World Trade Center (also known as One World Trade, One WTC, or Freedom Tower) is the main building of the rebuilt World Trade Center complex in Lower Manhattan, New York City. 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. (Wikipedia)
One WTC is the tallest building in the United States, the tallest building in the Western Hemisphere, and the sixth-tallest in the world. Floors 100-102 of the building is the One World Observatory, an enclosed observation deck rising 1,250 feet above street level offering unobstructed views of the spectacular New York City skyline.
