Burg Isenberg Castle
This old ruins castle is located just in the outskirt of this small city at the top of the hill. To get to the castle you can take a short walk through the forest road up the hill.
I saw this small house somewhere outside the old city, I was really wondering, is someonw really lives here? well, at list it makes the cleaning job easy ;-)
There is this old wall around the old city. You have to walk to the edge of the city to see it, not much left of it, but the parts that are there are very nice.
