One of the oldest murals in Saint-Petersburg was created during the international graffiti forum "Meeting of styles" in 2008 by several artists from different countries.
The wall is 37m high and has 10m length: the topic of the painting is cooperation and communication — tree is made of graffiti tags and illustrations.
The wall was supposed to be one of the 100 legal walls accessible for street art painters, but project failed and now this is more of the exception.
