Steinenschloss

Very interesting castle ruins. A detour to the "Rieslocher gorge is worth it".

If you climb up the hills on the eastern outskirts of Thaleischweiler-Fröschen from the Schwarzbach valley, you will soon reach an extraordinary castle complex: the stone castle.
A mighty round tower with a diameter of more than 13 meters towers above the partially restored Salian-Staufen castle ruins. Similar tower structures can only be found in central Germany.The stone castle was built during the reign of the Salian emperors, around 1024-1125. The stone castle, which can only be admired as a ruin, with its mighty sandstone blocks at the confluence of the Schwarzbach and Rodalb, is proof of how the Salian Emperor Konrad II pushed back the dukes and church in their special powers.If you climb up the hills on the eastern outskirts of Thaleischweiler-Fröschen from the Schwarzbach valley, you will soon reach an extraordinary castle complex: the stone castle.
