Aside from Berlin's more attractive architectural sites, the German capital is known for its sprawling concrete housing estates. Locally referred to as "Plattenbauten", the estates were constructed in the post-War era to curb the country's housing shortage. As a part of local efforts to brighten three buildings in the eastern district of Friedrichsfelde, a group of artists covered 22,000 square meters (72,000 square feet) of concrete with a zoo-themed mural. Artist Steven Rolle was pictured on Tuesday putting the finishing touches on the installation, which will be officially unveiled on August 22. The application for a place in the Guinness Book of Records -- for the world's largest mural on an inhabited building -- is still pending.
