Russian wedding tradition: Love locks

I have seen this in Irkutsk and also in Moscow. In Irkutsk, newly married couples place a lock with their names and wedding date on the railing of the walkway alongside the Angara River. Then they throw away the key into the river. Pretty straightforward in its meaning, and also quite beautiful. Hopefully the fish don't try to eat the keys and get sick or die.

In Moscow, I saw this same tradition but the locks are placed on a sculpture of a tree on a bridge over the Moscow River. A few days ago there was a wedding in progress when I was crossed the bridge in Moscow. Everyone was drinking and smoking and the newlyweds shattered their champagne glasses on the bridge. The photo below is from Irkutsk, though, and the photo below that is the same walkway alongside the Angara River, but from a distance.
