Throwing Doves

This golden statue stands on Hermannplatz, a lovely ugly place in Berlin-Neukölln: half hipster, half sleazy.
What does it symbolize? I don’t know … freedom for children? Dance? (it was built in 1985 and the group of figures was originally rotatable but they stopped it 2012).
Doves like to sit on the guy‘s hand and on the ground.
