關於

The Heidelsburg, also called the Bunenstein, is an old fortification in the western Palatine Forest in the German state of Rhineland-Palatinate that goes back at least to the days of the Roman Empire. Today only the remains of two gates, together with their steps, the castle walls and a cistern have survived.
