Cologne Government Region

Cologne Government Region (German: "Regierungsbezirk Köln", Kölsch: "Rejierungsbezirk Kölle") is one of the five governmental districts of the German Federal State of North Rhine-Westphalia. It is in the southwest of that state. It covers the hills of the Eifel as well as the Bergisches Land.
It was made in 1815, when Prussia reorganised its districts.
