A map of the Electorate of Cologne showing major cities of the Electorate (Cologne, Bruhl, Bonn) as well as towns involved in the War and other important cities in the area.
The outline of the Electorate is based on Willem and Joan(nes) Blaeu's 1645 map File:Blaeu 1645 - Coloniensis Archiepiscopatus.jpg.
The gray lines show modern day national borders. Except for the Emscher river, the rivers are shown in their modern routes/channels/paths.

This map uses a Mercator projection.
