We all know what locks are conventionally used for and may think we know how to use them, but locks are also symbolic of other abstract things such as love. The history of love locks goes back 100 years ago to a Serbian tale of a WWI of a heartbreak.

Since then there are many european cities and landmarks that are notorious for love and lock locks.
