Pont du Carroussel in Paris

You're standing at the Pont du Carrousel, the bridge that carries you across the Seine from the Quai Voltaire to the Quai des Tuileries, right beside the Louvre. Look across to the other bank. The bridge lands exactly at the passages through the Louvre, and if you look closely, the Arc de Triomphe du Carrousel sits in a straight line behind them.
