This city map of Essen contains only the city and quarter boundaries of the 50 quarters, so that the file becomes not too large. The small photos contain the references to further information. I am still searching for better photos. But I would'nt make this page without pictures..hi In the meantime Google offers an immense number of information and photos about Essen.
