One World Observatory sits on the 100th, 101st and 102nd floors of One World Trade Center, at the corner of West and Vesey Streets in Lower Manhattan. Its operator describes it as the highest point in New York City, with views from above 1,250 feet. The building under it is the one the city built to fill the gap left by the World Trade Center, and its height was chosen as a symbol: 1,776 feet, for the year of the Declaration of Independence. This article covers how the tower was designed, how the observatory came to be there, and what the official sources say about visiting it.

Who designed One World Trade Center?

Skidmore, Owings & Merrill designed it, with David Childs as the architect. The firm's project page gives a building height of 1,776 feet, 104 stories, about 3.5 million square feet of gross area and a completion year of 2014. The World Trade Center timeline says plans for a 1,776-foot tower were unveiled on December 19, 2003, and that construction began on April 27, 2006. It also says the Port Authority renamed the Freedom Tower as One World Trade Center on March 27, 2009, on the reasoning that the name would make the building more marketable for tenants and the public.

The same timeline says the design was changed because of security concerns raised by the NYPD and then-Governor George Pataki. Details such as the 1,776-foot height and the 276-foot spire stayed the same. The tower was set back farther from West Street, and the timeline says it would have no occupied space other than its lobby at the base.

Is One World Trade Center really 1,776 feet tall?

It is, but the count includes the spire. A Port Authority news release says crews installed the final two sections of a 408-foot steel spire, and that the building then stood a symbolic 1,776 feet high, the tallest in the Western Hemisphere. The World Trade Center timeline dates that to May 2, 2013. The Associated Press reported on November 12, 2013, that the Council on Tall Buildings and Urban Habitat had ruled that the needle counts as part of the building's height, which made it the tallest building in the United States. Without the needle, the AP says, the tower would be 1,368 feet, the same as the original World Trade Center.

That ruling matters when you read the word "highest." The 1,776 feet is the height of the building including its spire. The observatory is lower, on floors 100 to 102.

How did the observatory come to be?

The 2003 plans for the tower included a public observation deck, according to the World Trade Center timeline. The Port Authority then selected an operator. A New York Times report from March 2013 said the Port Authority was expected to approve a 15-year deal with Legends Hospitality Management to run the deck, a contract officials said could generate as much as $875 million in revenue for the authority over its life. The Times projected 3.5 million visitors a year. It also said the observatory would open more than 1,230 feet above Vesey Street, while the operator's later materials say 1,250 feet. The sources differ on that number.

One World Observatory opened to the public on Friday, May 29, 2015. The operator's announcement said the preview days before it included local students, the workers who built the tower, and a first-come open house for the public. At launch, the announcement said adult tickets were $32, child tickets $26 and tickets for seniors $30. The announcement says all tickets were timed.

What is inside?

The operator's 2015 announcement describes a visit that starts at the ground floor in the Global Welcome Center, with a pre-show called Voices about the people who built the tower. Visitors then board one of five Sky Pod elevators to the 102nd floor. The announcement said the ride would take under 60 seconds. The operator's current site says the ride takes 47 seconds, so the sources differ, and the current figure is the operator's own. The elevator ride shows a time-lapse of New York's history, according to both CBS in 2015 and the operator's site today.

On the 102nd floor visitors reach the See Forever Theater, which shows a short film of the city. The 100th floor is the main viewing level. The 2015 announcement describes City Pulse, a skyline "concierge" where ambassadors use gesture recognition to bring up close-up views of landmarks. It also describes the Sky Portal, a 14-foot disc in the floor that shows real-time footage of the streets below. CBS reported that the Sky Portal feed comes from a camera on the spire. Dining is on the 101st floor, and the 102nd floor is an event space. The operator's ticket page says a standard ticket covers all three levels, floors 100 to 102.

The operator's current site says the observatory covers more than 125,000 square feet across the three levels. It lists a restaurant called ONE Dine on the 101st floor and a bar called ONE Mix, and recommends reservations. Its FAQ says dining and cafe options are only open to ticketed guests of the observatory. The site also says live tour ambassadors on the observation floor point out neighborhoods and landmarks.

CBS also reported in 2015 that there is no outdoor space at the observatory. Its operator said the building's design would not allow it. If you want an open-air deck, that is a different attraction.

Is it the highest observatory in New York?

That is what the operator says. Its ticket page describes panoramic views "from the highest point in New York City," and its site calls One World Trade Center the tallest tower in the USA. The New York Times said in 2013, before opening, that the deck would sit among the highest in the nation, passing the Empire State Building's deck by a few feet. This article repeats the claim as the operator's own, and does not rank other observation decks, which have their own sources.

What was there before?

The original World Trade Center had its own observation deck. The timeline says the Top of the World observation deck opened at the South Tower, on the 107th floor, and that on a clear day visitors could see up to 50 miles in any direction. The original Twin Towers were designed by Minoru Yamasaki and stood at 1,368 and 1,362 feet on 110 floors each. The new tower was built after the attacks of September 11, 2001. The Times describes it as a symbol of what officials call the city's resilience. CBS noted in 2015 that, apart from the memorial pools far below, the observatory makes no explicit reference to the attacks.

Who owns One World Trade Center and runs the observatory?

SOM's description of the project says the building is owned by the Port Authority of New York and New Jersey, with the developer Durst Organization holding a 10 percent stake. The New York Times reported in 2010 that the Port Authority approved a partnership that gave the Durst family a share of the tower. The Durst Organization says it leases and manages the tower with Newmark. The observatory itself is run by Legends under the Port Authority's contract, according to the operator's 2015 announcement, which names Legends as the operator. Check the operator's site for current management.

Where can you eat or drink at One World Observatory?

The observatory's current dining page lists the following.

ONE Dine, 101 stories up, New American menu. Daily 2:00 PM to 10:00 PM; the kitchen closes at 8:00 PM and last call for drinks is 9:30 PM. A ticket to the observatory is required for a la carte reservations.
ONE Mix bar and ONE Café (the page names an illy Caffè and Gelateria). The observatory says dining is for ticketed guests.
