Where did the love padlock idea start? Some say Serbia, some say Italy... Anyhow, now you find them all over the world.
In Paris, especially the "Pont des Arts" was originally concerned. I posted aobut it e.g. here and here. In 2010 most of the padlocks mysteriously disappeared from "Pont des Arts". No local authorities admitted having been behind this. The rumour said it could have been done by an art student... Today, "Pont des Arts" is thus again well covered, but you can still see through. I took a few new photos the other day.
However, today an even higher concentration of padlocks can be found on the “Pont del’Archevêché” (see my post from 2008 – when there were not yet any padlocks). The bridge is today completely covered, and here you cannot see through… (see also top picture).
I'm still in Sweden. This post is preprogrammed.
