There is a bridge in Paris, the Pont des Arts, that everyone calls the Love Locks Bridge.
Since 2008, couples, families, and friends have been attaching locks to the bridge's sides. Most people write their names on the lock and attach the lock to the bridge. Then they throw the key into the Seine River. Once the key is in the water, it means that no one can break their love or friendship.
By the spring of 2014, there were almost 1 million locks on the Pont des Arts. This was too much for the bridge. In June of that year, one of the railings collapsed under the weight of all the locks.
The city of Paris does not love the love locks. They tried to remove them, but people just put more locks back on. After the railing broke in 2014, they tried putting glass over three sections of the bridge.
Love locks have become a worldwide symbol of love and friendship. Bridges, fences, and poles around the world have become packed with them.
