It is neither a stella nor a construction of the Second World War intended to test the speed of ships. It is a beacon (marine marker) intended for boats approaching Groix. As evidenced by the black and white paint affixed on the sea side (like most lighthouses)

This somewhat bizarre and eccentric man-made construction is believed to be a beacon used on the warship speed test route just before World War I.
