Did Tsereteli donate $12 million of his own money to build the Tear Drop Memorial? Did Russia commission the building of the sculpture?

Russia commissioned the building of the sculpture. It is from the Russian People and their president Vladimir Putin

Is it true that it was demolished?

It's a shame..it's such a beautiful piece and ur tucked away in a forgotten corner with no signs directing anyone into it..if you don't know specifically what you're looking for is very difficult to find
