The observatory of New York's new World Trade Center will open May 29 to the public, building managers said Tuesday.

The observatory is on floors 100, 101 and 102 in the gleaming glass tower that was built on the site of buildings destroyed in the September 11, 2001 attacks in Manhattan.

Also known as One World Trade Center, the building houses the highest offices in the Western Hemisphere. From a height of 1,250 feet (380 meters) visitors to the observatory will be able to see across much of the city of New York's famous streets and parks.

The main viewing area is on floor 100, floor 101 features a cafe and restaurant and floor 102 includes a 3D tour of the city.

Entrance fees are $32 for adults, $30 for seniors and $26 for children.

The observatory will be open seven days a week from 9 am to midnight this summer and hours will change in September. One World Trade Center was completed in late 2013 and its first occupants moved in shortly after.
