Koenigsberg
Königsberg was a city in Eastern Prussia. Since World War II the whole area was taken over by the Soviet Union under Stalin and the city was renamed Kaliningrad in the Kaliningrad Oblast, today Russia.
It borders with Lithuania in the East/North-East, the Baltic Sea in the West and Poland in the South.
Polish name: Krolewiec
Statement by Joost Lemmens : Ref. East Prussia name: I would like to remark that the current Russian inhabitants of the region call their homeland this way (Vostochnya Prussia -- no, maybe not the military and top officials, but the common people anyway) -- just because it IS East Prussia, and they see no need to hide this fact. In fact they are generally quite interested in and open-minded about its German past.
Even the town of Kaliningrad is still being called "Kënigsberg" or simply "Kënig" by the man in the street, as well as this name being used by many local enterprises.
