This 0.60 franc French postage stamp, issued in 1966, celebrates the Usine Marémotrice de la Rance—the world’s first large-scale tidal power station, located near Saint-Malo, Brittany. The design by Chaley portrays a panoramic view of the Rance estuary, showing the dam stretching across the water with sailboats dotting the tidal basin beyond. The serene maritime scene highlights France’s innovation in harnessing renewable energy from ocean tides, marking a milestone in the country’s postwar industrial achievements.
