The Eger Creek flows through three cities and 13 villages during its 25 mile journey. This waterway was a vital source for irrigation and was populated with flour and sawmills from the 17th through the 19th centuries. Eger is located in the fertile River Eger Valley between the Mátra and Bükk mountain ranges. These hills are covered with vineyards. The city’s name is derived from the Latin word “ager” which means “earth.” The river bisects the old town from the base of Castle Hill.
