Schloss Harburg
At the point where the little Wörnitz River breaks through the Franconian Jura Mountains, 20 km (12 miles) southeast of Nördlingen, you'll find one of southern Germany's best-preserved medieval castles. Schloss Harburg was already old when it passed into the possession of the count of Oettingen-Wallerstein in 1295; before that time it belonged to the Hohenstaufen emperors. The same family still owns the castle. The castle is on B-25, which runs under it through a tunnel in the rock.
