From different perspectives, viewing the Manhattan skyline can bring different aesthetics, but the most eye-catching one is always the tallest building in New York, the New World Trade Center on the 104th floor, which is 546 meters high. The new building is built next to the collapsed Twin Towers of the World Trade Center, also known as the "Freedom Tower". On the exterior wall of the building, there are two airplane models located at the height of the 9/11 plane hitting the Twin Towers, to warn people that freedom is hard won.
