This is the famous Zagreb Grounded Sun made by Croatian artist Ivan Kožarić in 1971. It was quite controversial when it was made - so much that it was set on fire, bombed, devastated and much more. Today, people have get used to it and even got to like it a lot. It is covered with real gold but because of this incredibly stupid custom of people signing themselves on it (Note: it is forbidden to do that!) you are not able to see it in it's true beauty. Also, it is a part of Zagreb Solar system that I told you about before. You can find it in Bogovićeva street that's between Zagreb main square and Petar Predradović square.
