The so called “Kyffhäuser” is a low mountain range in mid Germany southeast of the mountain of the Harz. Here at the end of the 19th century the Kyffhäuser-Denkmal as National Monument has been built to the honor of emperor Wilhelm the 1. (What a sentence!) We do our daily exercise here because many may steps leed up to the monstrosity.
And you can also climb up inside the monument. The best thing is the view you have up there.
As the saga th German Emperor Friedrich 1. Barbarossa sleeps in a cave of the Kyffhäuser Mountain. When the time comes he will wake and save Germany. During his sleep his beard grows and grows around a table of stone. Up till now the beard has rounded this table two times. After the third round the end of the world will come.
