Mont Sainte-Odile (German: 'Odilienberg' or Ottilienberg; called Allitona in the 8th century) is a 764-metre-high peak in the Vosges Mountains in Alsace in France, immediately west of Barr.

[3] At least since the 19th century, its beauty has been celebrated[4] and the mountain, with convent and pagan wall, is often included in tourist guides,[5] incl.

[6] The convent is said to have been founded by Adalrich, Duke of Alsace, in honor of his daughter, Saint Odile, about the end of the 7th century, and it is certain that it existed at the time of Charlemagne.

The Pagan Wall (German: Heidenmauer, French: Mur païen) is a huge construction about 10 kilometres (6.2 mi) long which encircles Mont Sainte Odile.

The irregular shape of the wall coincides almost perfectly with the location of outcrops of its source material, minimizing the effort to transport the heavy blocks to their destination.
