I often admire Berlin for colourful blocks of flats instead of grey boxes which can be seen everywhere in post-soviet countries. Berlin could have easily been the most depressing city in Europe, but artists turned it into the world of colors. Now the walls of the city are pained in animals, flowers, butterflies, faces and other funny creatures. Recently a team from a French firm CitéCréation painted the wild life on the row of apartment blocks, which, they hope, is now the World’s Biggest Mural. The mural was inspired by a nearby zoo and covers an impressive 20,000 square metres of wall facing the street. The mural features birds, bears and even imaginary residents are interacting with the painted wildlife that adorns the Wohngenossenschaft Soldaritaet Coop apartments in the German capital.
