One World Observatory opened on May 29, 2015, on the 100th, 101st and 102nd floors of One World Trade Center. It offers stunning panoramic views of New York City and the surrounding area.
The building is the nation’s tallest, at 1,776 feet. Visitors get a view of the city from 1,250 feet that stretches 50 miles past the Manhattan skyline and Statue of Liberty to the Atlantic Ocean.
Lower Manhattan, dominated by the financial industry, has also become one of Manhattan’s top tourist destinations, with memorials to the victims of the Sept. 11 attacks, shopping malls and historical landmarks.
