Where is this Koeln place that you speak of? It's not called that in any language. Köln or Cologne, but not some Anglicised transliteration of the German name please.
Meanwhile, Google maps seems to be living in some time warp, insisting on using English names that I didn't even know existed, such as Coblence and Mayence. Strange. It's not like the proper German names have umlauts.
