One World Observatory and New York City from above

One World Observatory occupies the upper levels of One World Trade Center, where glass walls frame Lower Manhattan, New York Harbor and the city’s wider skyline. The observatory opened in 2015 inside a tower that rises to 541 m (1,776 ft), making the building itself part of the experience.

Three levels above Lower Manhattan

One World Observatory spans floors 100, 101 and 102 of One World Trade Center. Its elevated rooms are enclosed rather than set on an exposed platform, with floor-to-ceiling glazing around the viewing areas.

The observatory sits at approximately 386 m (1,268 ft) above street level. From the glass perimeter, the Hudson River, New York Harbor, Brooklyn, New Jersey and the streets of Lower Manhattan form a broad urban view.

One World Trade Center’s vertical form

One World Trade Center was designed by David Childs of Skidmore, Owings & Merrill. The tower has a square base, a tapered middle and an elongated octagonal appearance, with a glass-clad exterior rising above the World Trade Center site.

The tower opened in 2014, while One World Observatory opened on 29 May 2015. Its three viewing levels sit within the upper section of the 104-storey building, above offices and other internal spaces. The building’s 541-metre height corresponds to 1,776 ft, a number associated with 1776 and the history of the United States.

A high interior view of New York City

The route through One World Observatory combines lift travel with exhibition and viewing spaces. The Sky Pod lifts rise through the tower before reaching the upper floors, where the city appears beyond the glass.

Views extend in several directions across the harbour and the metropolitan landscape. The observatory’s position near the southern end of Manhattan places the financial district, waterways, bridges and neighbouring boroughs within the same wide panorama.

One World Observatory forms part of the rebuilt World Trade Center complex. Its setting connects the high interior viewpoint with the surrounding streets, public spaces and memorial sites of Lower Manhattan. The tower’s David Childs design gives the observatory a distinct architectural setting rather than treating it as a separate structure.
