Many poets and writers had composed literary works expressing and symbolizing the many gesture of love. These literary artists came from all over the world making them revered poets and novelists. One gesture of love however is quite a new concept that particularly started before the 21st century. It involves two people madly in love, a padlock and a bridge. The result of this romantic endeavor is called the Love Lock Bridge.
The Love Lock Bridge today is particularly popular in Europe and some parts of the United States and Asia. The most famous one is in Paris (of course!) at the Pont des Arts Bridge just northwest of the Ile de la Cite. The second most famous one, I believe I found on my recent trip to Cologne in August 2015. The south side fence in particular of the Hohenzollern Bridge in Cologne is filled with locks of all sizes and shapes. Some have inscriptions etched on them with the names and important dates for the couple. Others were quite plain and simple as the gesture is more important than the aesthetics. Even though the Hohenzollern Bridge is the busiest in all Cologne (it is the bridge that serves Deutsche Bahn trains) it is also one of the most visited sites in the city second only to the Cologne cathedral, possibly because it is easily accessible and free. Many visitors would stand and read some of the inscriptions written in the locks. I know I did.
City and Deutsche Bahn officials in the past threatened to remove the locks when they first started appearing on the bridge but they face some serious public opposition and in the end the locks remained. To those who had contributed to the growing number of padlocks clamped on this bridge, there is no greater power and force than the commitment between two people to be together for the rest of their lives. The locks therefore stayed on the bridge for posterity.
