love locks in Munich

I’ve seen pictures of padlocks covering the Pont des Arts bridge in Paris, but I was surprised to see them also in Munich, on a bridge over the Isar river that we crossed to get from the subway to the zoo. 

I think this is such a sweet custom in theory, but most of the engraved locks appeared to be new, and were the same brand and size, making me think they are being sold as a tourist gimmick somewhere close by the bridge. 

The locks definitely added some much needed color and charm to the simple chain link fence, and it’s very romantic in theory, but does it kind of cheapen the love locks a bit if they become ubiquitous?
