The bell towers of the Notre Dame de Paris standing tall behind the Quai aux Fleurs. The building with the long rectangular plaque between two rounded doors is where in 1118, in a residence since destroyed, Pierre Abélard and Hélouise d’Argenteuil lived a moment of their forbidden love affaire. (P.S. This week’s Daily Photo will be dedicated to the River Seine. The most polluted and beautiful river in Europe.)
