Eifgenbach

Eifgenbach is a 20.5 km river of North Rhine-Westphalia, Germany. Its source is near Wermelskirchen, appr. 15 km south of Wuppertal. It runs in south-westerly direction, and its mouth into the river Dhünn is near Odenthal, appr. 15 km north-east of Cologne.

460 acres of the river basin of the Eifgenbach and its tributaries have been declared nature reserve in order to protect its bio-diversity.

About 1 km below the mouth into the Dhünn lies the Altenberger Dom, a monastery church built from 1255 on by Adolf IV, Count of Berg in Gothic style. Today the church belongs to the German state of North Rhine-Westfalia and is used both by the Protestants and Catholics as shared church.
