one of my favourite sights from my trip to paris was found completely by accident. after walking through the courtyard of the louvre (although i didn't actually go in the gallery as the queue was like 3 hours long), we crossed the road to wait for the sightseeing bus & on the bridge behind us were hundreds and hundreds of padlocks.
i'm not sure what tradition/superstition this is, or even the name of the bridge, but lots of the locks seemed to have inscriptions of names & hearts, so i'm guessing it's something to do with wishing for everlasting love. after all, paris is the city of love.
i just loved the huge range of locks that were there, all kinds of colours, shapes and sizes. some were old, plain & rusty and some were shiny and newer-looking.
some had no writing whatsoever, some had rudimentary initials daubed on in tip-ex or paint, and some had personalised & poetic inscriptions. i think this is such a lovely thing to do, and i truly was amazed.
