Most sources seem to agree that the tradition began in the city of Pécs in Hungary, sometime during the early 1980s. Smitten students started hanging padlocks on an iron fence linking the main square to the medieval cathedral. Within a short time, the fence was completely covered with declarations of love and, nowadays, Pécs has gained a reputation as a paramount romantic destination.
However, in China, it seems that locks and keys have been used to symbolise love, marriage and eternal commitment for a great deal longer. Nowadays, one of China's most famous scenic locations, Mount Huangshan, has become a popular spot to attach a love padlock. Thousands of lovelocks hang from Lotus Peak's chain fence, placed by tourists from all around the world. Lovers throw the keys into the abyss below, thus locking their memories to the Hunagshan Mountain forever.
