The Limes Germanicus, contains parts of the limes from old ancient Roman provinces like Germania Inferior, Germania Superior and Raetia, stretching on approximately 550 km. The Limes Germanicus separated the Roman Empire from Germanic tribes.

The Limes part covering the old province of Germania Superior and Raetia was constructed during the reign of Hadrian during the beginning of A.D. II-nd century and the middle of the III-rd century. The frontier stretched from the river Rhine to the Danube, crossing the today’s federal states of Baden-Württemberg, Bavaria, Hessen and Rheinland-Pfalz. All along the limes we find, castra, watchtowers, artificial barriers and civilian settlements.

In 2005, the limes part covering the former provinces of Germania Superior and Raetia entered the UNESCO World Heritage List.
