Windorgel Vlissingen

Windorgel Vlissingen is a wind-powered sound sculpture on the Nolledijk seawall near Vlissingen, Zeeland, in the Netherlands. First installed in August 1975 by Belgian artist Raphaël August Opstaele and the collective Mass Moving, it was the sole realized fragment of the Sound Stream project, an unbuilt plan for a chain of wind organs from West Africa to the North Pole. Built from tall bamboo pipes on a former WWII bunker, it converts sea wind into a shifting drone, from low hum to storm-driven howl. A 1976 gale destroyed it and vandals later cut its pipes in 1981; each time, local fundraising rebuilt it. It remains the only known surviving permanent wind organ.
