Also called the Lock­ing Bridge. If you walk to the back of the KAlner Dom along a straight path, there is a bridge on the Rhine to your right that is cov­ered in pad­locks. The locks are placed there by cou­ples to show their loy­al­ty to each oth­er. Cou­ples often have their names and a sig­nif­i­cant date inscribed on the locks. There are oth­er places across the world that have love pad­locks.
