Starry-eyed tourists from all over the world flock to the Pont des Arts bridge spanning the Seine River to attach a lock representing their eternal love, and throw the key into the river.
But the now-iconic bridge is buckling under the weight of such devotion, and authorities are desperate to stop the craze.
Last year police hurriedly ushered tourists off the Pont des Arts when a section of the footbridge collapsed under the weight of the locks covering the 155-metre-(509-foot-)long bridge.
But nothing stands in the way of true love, and tourists have kept piling the locks on the bridge and elsewhere.
