Arches on the Seine--Paris, France

There's something alluring about an arch--it creates a subtle line for the eye to follow. The curves of the bridges along the Seine, one after another, create the perfect frame to view the city as one walks riverside. As one walks the Seine's path, passengers wave to you from the ferry and you can peer into the house boats docked along the river bank, getting a glimpse of how life would be like traveling Europe by boat.
