The One World Trade Center is also known as the New World Trade Center and you can find it in New York City as part of the Lower Manhattan skyline. The skyscraper is 1,776 feet tall, a number which was no coincidence, and features new architectural designs. The observation deck just opened in 2015 and is called the One World Observatory. There are three different levels to the observatory, which is 1,250 feet higher than the street. The elevators are able to reach the top in around a minute and you can also eat, shop, or host events at the top of the skyscraper.
