The main observatory, located on the 100th floor, will include an interactive skyline "concierge," allowing guests to connect with the iconic sites and surrounding neighborhoods they observe from above. Guests will also be invited to step onto a 14-foot wide circular disc that will provide an unforgettable view.

"From sweeping panoramic views, to innovative interactive exhibits, to world-class dining options, we expect One World Observatory to be the premier destination and attraction in New York City for both tourists and local residents," said David Checketts, chairman and chief executive officer of legends, operator of the observatory.

In the days leading up to the grand opening, the observatory will invite school students and workers who helped build One World Trade Center to get a first look.
