This photo was published in 1922 in The Book of Radio, Charles William Taussig, pages 312-327, to illustrate a chapter on the opening of "Radio Central" Radio Corporation of America's (RCA) at Rocky Point, Long Island. earlyradiohistory.us/1922RCA.htm The Rocky Point Historical Society website account: "In July of 1920, RCA began construction of their main Operating and Administration Building #1. It was built in mediterranean architecture of cream-colored walls, with brick trim, accented with arched windows and an overhanging roof of ceramic red tiles. A large wooden door, trimmed with studded nail heads and a carved brass handle, opened into an entrance hall. On November 5, 1921 President Warren C. Harding pressed a button in the White House in Washington, D.C. which officially opened the RCA Radio Central facilities at Rocky Point. Radio Central was considered the largest transmitting station in the world. Originally, long waves were used, resulting in the construction of six 410 high steel towers. The towers were 410’ high with added cross-arm of 40’ high, extending the total height to 450’. The tall height of the structures was necessary for the long distance, worldwide type of radio communications. The twelve towers, which were 1260 apart, covered a two and a half mile area. Tower #1 remained standing tall, with its flashing red beacon guiding planes and ships, served as an aviation beacon light for another sixteen years. AT 2:30 PM on December 13, 1977, the 56-year-old tower was the last to come down." www.rockypointhistoricalsociety.org/rca-radio-central/
