The padlock buckle was inspired by love; the legend goes that a woman who had lost her lover during World War I started fixing padlocks on bridges where they used to meet. It was her way of expressing that her love was unbreakable. Soon, the trend caught on and became a tradition in many parts of the world.
Since the 2000s, love locks have proliferated at an increasing number of locations worldwide >> those cities you will see above >> "PADLOCK YOUR LOVE WITH A CM® BUCKLE" >> a love lock or love padlock is a padlock that pairs lock to a bridge, fence, gate, monument, or similar public fixture to symbolise their unbreakable love; and now I 'unofficially' add 'waist' to the list.
