Nice pictures.

Regarding the locks, I don't name the name of it either, but it seems to be a common tradition for young couples in Russia.

I distinctly remember while walking to the soccer stadium in Kiev crossing a bridge, and the girl I was with told me it was the мост любви (bridge of love). There were hundreds of padlocks attached to it. If I understood the girl I was with, she said couples will paint/write their names on the lock, lock it to a place of significance (perhaps a place they've kissed, or as in your picture, where they got married), and then throw away the key to sort of symbolize their unending love.

Here's a picture I found of the bridge in Kiev:



A bit cheesy.
