Lafayette radio-telegraphic station built in Croix d'Hins, France started operation in 1920.
Conceived for the purpose of insuring adequate and uninterrupted (day/night) transatlantic communication facilities between the American Forces engaged in World War I and the government of the USA, radio-telegraphic station, the most powerful of the world at that time, was built in "Croix d'Hins" near Bordeaux, in collaboration between the US Navy and France. Station was actually finished after the war.
A team of 750 US Marines was sent to build the eight 250 meters high towers.
US Navy provided towers and transmitters
France provided antenna system, tower bases, buildings, energy supply.
Station was destroyed in 1944 by the Germans.
Last remaining tower (used for fire monitoring) was destroyed in 1953.
