Opened in 2015, at the top of the Freedom Tower, this observatory is loaded with meaning – due to the September 11 attacks – and in a way symbolizes the city's resilience and its power of reconstruction. It is the tallest skyscraper in the Western Hemisphere. The One World Observatory, in a way, started a trend in tourist attractions that has been growing more and more: it initiated an era where places not only offer what they propose, but also a complete experience, a plus that stirs people's feelings.

The observatory – the building is about 350 meters tall and the observatory is on the 102nd floor, providing a 360-degree view of the city. On a clear day, you can see more than 50 km away. From up there, you can see the Statue of Liberty, Brooklyn Bridge, Manhattan Bridge, Williamsburg Bridge, Empire State Building, New Jersey, Hudson River, Staten Island, Brooklyn, and so on.

The experience – Before reaching the elevator, you pass through corridors with several screens displaying images of testimonials from people who worked on the construction. As you go up, the elevator walls show the development of the city, from the year 1500 to the present day. It's so real that you get the impression that there's nothing separating you from the outside world. Before reaching the observatory itself, you'll come across a huge wall, like a cinema screen, that will show an inspiring video of the city – it's moving. The video lasts a few minutes and, at the end, the screens go up and show the real view of the street.
