Love Lock Bridge, Paris---I was just there! and what a stunning view from the bridge! The lock idea is really interesting too, and the story that goes with them :) Even if it's not good for the bridge.
Pont des Arts "Love bridge", Paris, France - The Pont des Arts crosses the French capital's river Seine just in front of the Louvre museum and is known the world over for its "locks of love". The Seine river must be brimming with keys!
