Love locks are padlocks that couples attach to bridges, fences, or other public structures to symbolize their love. The tradition involves inscribing the lock with initials or a special message, then securing it in place and throwing the key into the water below, signifying an unbreakable bond. This practice has become popular in many cities around the world, including Paris, where the Pont des Arts bridge was famously adorned with thousands of locks. However, concerns about structural damage and safety have led some cities to remove these locks, prompting discussions about preserving the tradition while maintaining public spaces.
