Covered in padlocks, many engraved with the names of lovers, the legend behind this particular tradition is remarkably modern. In 1992 Federico Moccia published a love story entitled Tre metri sopra il cielo, which told the story of two young Italian lovers who seal their everlasting love by attaching a padlock to Rome’s Ponte Milvio and throw the key into the Tiber River below, thus binding the pair to each other forever. While pure treacle, the book spawned a film, as well as ‘Love Bridges’ all over the world.
