Beginning in the 1980s, in the centre of the southern Hungarian city of Pécs, lovers began to clamp padlocks to a wrought-iron fence in a narrow street linking the mosque in the city's main square and the magnificent medieval cathedral, as a symbol of their commitment to one another. However, after the fence was completely covered and no more padlocks could be added, couples, both locals and tourists, began attaching them to fences and statues throughout the town centre.
Local authorities organised several attempts to discourage people from attaching the padlocks, by putting notices discouraging the activity throughout the town and removing the padlocks as vandalism. More recently, a new iron fence was added near the original one to provide a legal site for couples to attach love padlocks, similar to walls set aside by authorities in some cities for use by graffiti artists.

In Florence, Italy, love padlocks have been affixed to the railing around and near the statue of Benvenuto Cellini located at the centre of the Ponte Vecchio. The same happens in Rome, Italy, on Ponte Milvio, in Ventimiglia, Italy on the Passerella Squarciafichi between the old town and the new part of the town and in Turin, Italy, in several parts of the city. Perhaps the most famous example in Italy takes place on the Via Dell'Amore, a path connecting the towns of Manarola and Riomaggiore in the Cinque Terre. The pathway's legend holds that it was a meeting place for lovers from the two towns, and is now a favorite site for tourists to place their locks and throw the keys into the sea.
Love padlocks can be seen in Guam's "Two Lovers' Point" (Puntan dos Amantes).

A variation of this is the use of plastic bag tags that are sometimes purchased at the nearby souvenir shop when a conventional padlock is unavailable.
A fountain in Montevideo, on Avenida 18 de Julio a few blocks east of Plaza Independencia, is designated for love padlocks.
