WNYC Transmitter Park is a 6.61-acre public park located in the Greenpoint neighborhood of Brooklyn, New York City, where Greenpoint Avenue dead-ends by the East River shoreline. The site was acquired by the public radio station WNYC in 1935 as the site of twin antennas used for broadcasting. From 1937 to 1990, the city-operated station broadcast its AM signal from this location. Following the adoption of antennas in Kearny, New Jersey and atop the World Trade Center, the Greenpoint property sat unused. Ground was broken for WNYC Transmitter Park in August 2010, followed by two years of construction, with the park opening in September 2012.
