The World Trade Center Transportation Hub is the Port Authority of New York and New Jersey's formal name for the new PATH station and the associated transit and retail complex that opened on March 3, 2016. The station's renaming took place when the station reopened. It was designed by Spanish architect Santiago Calatrava and composed of a train station with a large and open mezzanine under the National September 11 Memorial plaza. This mezzanine is connected to an aboveground head house structure called the Oculus—located between 2 World Trade Center and 3 World Trade Center—as well as to public concourses under the various towers in the World Trade Center complex.
In addition, the station was designed to connect the PATH to the New York City Subway system, and to facilitate a below ground east-west passageway that connects to the various modes of transportation in Lower Manhattan, from the Fulton Center to the Battery Park City Ferry Terminal. Furthermore, to replace the lost retail space from the original mall at the World Trade Center, significant portions of the Hub are devoted to the new 365,000 square foot Westfield World Trade Center mall.
Herbert Muschamp, architecture critic of The New York Times, compared the design to the Bethesda Terrace and Fountain in Central Park, and wrote in 2004: “Santiago Calatrava's design for the World Trade Center PATH station should satisfy those who believe that buildings planned for ground zero must aspire to a spiritual dimension. Over the years, many people have discerned a metaphysical element in Mr. Calatrava's work. I hope New Yorkers will detect its presence, too. With deep appreciation, I congratulate the Port Authority for commissioning Mr. Calatrava, the great Spanish architect and engineer, to design a building with the power to shape the future of New York. It is a pleasure to report, for once, that public officials are not overstating the case when they describe a design as breathtaking."
