A love lock, sometimes known as a love padlock, is a padlock which couples lock to a public object, most often a bridge, to symbolize their love. After the padlock is locked, the key is thrown away, most often to a river or a lake, to symbolize their unbreakable love. Love locks have become more and more popular over the last 20 years and are often treated by the authorities as litter or even vandalism due to the damage they can cause and the cost of removing them
