While walking to the Kremlin, we saw all these people on a distance bridge and thought they must be taking pictures of the Kremlin or Ivan the Great Bell Tower. Well when we got closer we could see it was a lot of wedding parties and they were putting locks on the metal "Love Trees". It was pretty cool. I counted no less than 8 different brides. 1 groom had to pick his new wife up and walk up to the love tree at the center of the bridge... It was almost 90 degrees and he was struggling. It was a fun site to see. This place is really cool. If you come this was, bring a lock!
