The castle Wildstein was first mentioned in the early 14th century. Today, the plant located near Wildstein, municipality of Teunz in the Upper Palatinate district of Schwandorf is only preserved as the remainder of a castle stables.
The remains of the Burgstall Wildstein lie at 744 m altitude on a hill, southwest of the village Wildstein. The remnants of the complex can be reached from the village in ten minutes. On a clear day, the visitor has a magnificent panoramic view over the "Waldbuckel" of the Upper Palatinate Forest.
Nordgau called in the period around 1000 AD, the area of the middle and northern Upper Palatinate. The land was gradually colonized (clearing settlements in the vicinity are: Zeinried, Kühried, Pullenried, Wildeppenried) and the lands, in which the Slavs (Slavic settlements are: Teunz, Gleiritsch) from the East were already colonial advances. Castles therefore secured the area to the east. The Upper Palatinate is therefore the most densely casted area in Germany.
In the vicinity of Wildstein were the castles Kunzenstein, today a castle stable about two kilometers northwest, Flossenbürg, Leuchtenberg, Trausnitz, Tännesberg, Gleiritsch (Castle Plassenberg), House Murach (Obermurach), Thanstein, Reichenstein in Stadlern and Frauenstein in Weiding. In the Middle Ages, trade routes led east through the area. From the east, however, came again and again incursions to the newly populated areas of the Bavarian Nordgaus. The Castle Wildstein served, as well as the other castles, the administration of the area, the protection and control of trade routes and the defense against invasions.
