A PUBLIC OBSERVATORY will open at the World Trade Centre in New York next month.

The observatory will form the levels 100, 101, and 102 of the One World Trade Centre building in Lower Manhattan.

One World Trade Centre, as the tower is officially known, is a 104-storey, $3.9 billion project designed to fill the site of the September 11 terror attacks, which killed 2,606 people.

It is America’s tallest building and the centrepiece of the 16-acre site where the destroyed twin towers once stood.

The Observatory will feature a three-floor experience that will feature cinemas, a 14-foot HD “Sky Portal” and restaurants.

Here’s (roughly) what you will be able to see from that high up.

The observatory will open from 9am to midnight year round and tickets will be $32 for adults and $26 for kids.
