A love lock or love padlock is a padlock which sweethearts lock to a bridge, fence, gate, or similar public fixture to symbolize their love.[1] Typically the sweethearts' names or initials are inscribed on the padlock, and its key is thrown away to symbolize unbreakable love. Since the 2000s, love locks have proliferated at an increasing number of locations worldwide. They are now mostly treated by municipal authorities as litter or vandalism, and there is some cost to their removal.
