The Langenstein menhir (a 4-meter-high long stone) was erected in 1904 by a Soultzmatt industrialist, who recognized this block as an overturned menhir. Legend tells that on full moon nights, fairies, or White Ladies, come to dance around the Langenstein. During this ceremony, the stone is said to begin spinning!

One of the most beautiful climbs in the Vosges and a must to ride once. My favorite side is the one from Moosch or Soultz

The “Roche Sermet” is a rock formation located on the Hartmannswillerkopf¹ battlefield. It is located at an altitude of approximately **910 meters**². Hartmannswillerkopf, also known as Vieil Armand, is a pyramidal rocky spur in the Vosges massif, overlooking the Alsace plain from its 957 meters¹. During the First World War, it was a strategic summit hotly contested by the French and German armies¹. Today, the Hartmannswillerkopf is a place of memory, bearing witness to the suffering of the soldiers who fought in the name of their country¹. The German remains encountered on the ground, sometimes quite spaced apart from each other, are witnesses to this historical period¹.

Langstein means long stone. According to scientists, the block was extracted approximately 1km from its location. Its erection dates from the Celtic period, around 560 BC. It was rediscovered in 1904 lying on the ground by Fritz Keller, an industrialist from the region. It was straightened in 1906. A host of legends are linked to this Menhir. Listing them here would be too long.

There are now quite a few stickers on the sign. Good parking in the immediate vicinity (1km) to the summit.
