[blockquote]What is Love Lock Bridge?
No one is quite sure where the tradition of the love lock originated but love lock bridges have sprung up in cities around the world.
Lovers write their names or initials on a lock, attach it to a bridge, and throw the key into the water below when they are done. The superstitious believe that the only way to break apart the love that was sealed with a love lock is to open it with the key that locked it.[/blockquote]
