Tour Montjoie

ruelle de la tour, 78700 Conflans-Sainte-Honorine

Perched high above the Seine, the Montjoie Tower once kept watch over the river’s strategic waters. Now a peaceful sentinel, it watches over the barges of Conflans-Sainte-Honorine, the beating heart of inland waterway transport in Île-de-France.
