On the other side there is a cemetery, and quite a unique one at that. It's full of Russia's beloved artists, poets, politicians, ect. Almost every grave has a statue of the person who is buried there. Some were sad and mournful, others were lively and joyful. I don't know if other cemeteries exist like this one, but it was really cool.
I thought this grave on the left was really sad, it was of Stalin's first wife who was very young when they got married, and killed herself after a few years of marriage. It's not hard to guess why.
