    Hiking

    The "Heidenmauer" (Heathen Wall) surrounding Mount Odilienberg dates back to the time before Christ and was probably a protective wall against intruders, protecting the area on the mountain as a place of refuge. In some places, the wall is 2 meters wide and up to 3 meters high.

    About 10 km! you can hike past the Bronze Age here. I have no idea 🤷‍♂️ how people moved and above all hew the huge rock masses more than 3000 years ago.

    Hiking

    The Heidenmauer (French: Mur Païen) is a monumental, eleven-kilometer-long fortification from the early Middle Ages that encloses the high plateau of the Odilienberg in Alsace.

    The imposing structure has fascinated archaeologists and visitors alike for centuries with its sheer dimension and construction. Around 300,000 irregularly hewn sandstone blocks were piled up without mortar to form a dry stone wall up to two meters wide. To give the huge blocks stability, the builders connected them with swallowtail-shaped wooden clamps made of oak. This extraordinary technique secured the structure against the shifting of stones in the steep forest terrain.
