Isenburg castle, Hattingen
You must have strong legs to wander up to the hill of the Isenburg castle about 200 feet above the water level of the Ruhr.
But your afforts will be rewarded. The Isenburg castle ist not very big at all but it has been reconstruated in a very careful way during the last years.




But the view to the beautiful valley of the Ruhr will compensate your plains soon.
