The street art of Berlin is too diverse for a single post. Nor am I enough of an expert to be able to classify it into styles or periods. Instead I will post by areas. The photos you see here were taken just around the northern exits from the Heinrich Heine Strasse U-bahn station. The mural by Case McClaim is famous and probably the oldest in this set. The others were found opposite it and in the subway entrance just around the corner.
When Berlin was a divided city, this area contained a border crossing. At that time it was built up with cheap pre-fabricated housing, one block of which you can see in the general view of the area. The three chimneys belong to a modern (post-unification) power plant at which generates about half a gigawatt of electrical power. The plant simultaneously generates slightly more than this in useful heating supplied to the area. The plant was designed by the architect Jochem Jourdan. We did not have time to visit the artworks which are integrated with the power plant.
