Postamt 13

Postamt 13 (post office #13) in Hamburg is really an attraction - once the biggest telephone exchange station in Europe, a beautiful building changing its look during the year as the covering it rich ivy does. As I was drawing, a bypasser told me that the building was meant as a replica of fortress Marienburg in Danzig - I haven't found any information on that, but at least in part the fortress outline looks similar indeed.
