The Marconi Wireless Station Site sits on the dunes above the Atlantic in South Wellfleet, within the Cape Cod National Seashore, where Guglielmo Marconi built the transatlantic wireless station from which the first complete wireless message from the United States to Europe was transmitted on January 18, 1903. Only ruins remain: concrete floors and footings of the transmitter house, a connecting corridor, fragments of the brick powerhouse, and the rubble-and-cement bases of the antenna towers, much of it eroding toward the sea. The original circular ring of twenty 200-foot masts was destroyed by a storm in 1901 and replaced in 1902 by four 210-foot latticed wooden towers; the station, powered by kerosene engines and a spark-gap transmitter producing about 30,000 watts, served ships at sea until it was shut down and dismantled between 1917 and 1922. Cited for its significance in communications, engineering, and military history, it is described in the nomination as the only nationally significant historic site within the Cape Cod National Seashore.

This marker recalls the Marconi Wireless Station that Guglielmo Marconi built at South Wellfleet on the Cape Cod bluffs. From here on January 18, 1903, the first transatlantic wireless message to originate in the United States was sent, carrying greetings from President Theodore Roosevelt to King Edward VII of Britain at Marconi's companion station in Poldhu, Cornwall. The installation used towering wooden antenna masts and powerful spark transmitters, and its operators played a role in relaying news of the Titanic disaster in 1912. The station closed in 1917, and its eroding site is now preserved within the Cape Cod National Seashore.
