The summit of Mont-Ste-Odile is ringed by Mur Païen: an eerie 9½-km-long (6-mile-long) wall, which is up to 12 feet high and, in parts, several feet thick; its mysterious origins and purpose still baffle archaeologists. What is known is that the Romans established a settlement on the mont and, at the start of the eighth century, Odile (the patron saint of Alsace, who had been born blind) founded a convent on the same spot after receiving her sight while being baptized. The relatively modern convent is now a workaday hostelry for modern pilgrims on group retreats. Odile died here in AD 720; her sarcophagus rests in the 12th-century Chapelle Ste-Odile. The spare, Romanesque Chapelle de la Croix adjoins Ste-Odile.
