Port of New York Authority Building,1949.

Pedestrians crossing West 15th Street on the west side of Eighth Avenue; April 18, 1926. Every building on the blockfront behind them, between West 15th and 16th Streets, would be razed in the following years, making way for the city's largest building. The mammoth Port Authority Building (now Google's New York headquarters) was completed in 1932.

Port of New York Authority Building, 1941.

New York Port Authority building, 1937. 111 Eighth Avenue is an enormous building which takes up the entire block between Eighth and Ninth Avenues and 15th and 16th Streets. It is 2.9 million square feet and was the largest building in the city until 1963. Built in 1932 in the Art Deco style and designed by Lusby Simpson, the mammoth building was original constructed to be multi-use, with the first floor and basement used for the movement of goods by truck under the auspices of the Port Authority, and the upper floors used for manufacturing. With changing transportation and the dwindling of railroad freight in Manhattan, the original trucking functions of the building were largely abandoned by the mid 1940s. The building served as the headquarters of the Port Authority from the 1940s until the WTC opened in 1970. Since 2010 the building has been owned by Google (they paid a reported $1.9 billion), though other companies continue to rent space, including Nike and Bank of New York.
