One World Trade Center, named after the northern Twin Tower which was tragically lost on 9/11, is now the tallest building in all of New York City. The building is located in the lower-east side of Manhattan, within the financial district. Standing at 1,776 feet tall, the supertall structure contains 104 floors. Many of the world’s most prolific companies have offices located within the building. At the top, from floors 100 to 102, rests a three-story observation deck. Visitors have the opportunity to view Manhattan from the tallest point, providing a panoramic view of the entire city.
