The Fortified Sector of Rohrbach was built somewhat later than its neighbors to the east and west, and in company with positions on the extreme western end of the Maginot Line, became one of the "New Fronts."

Aware of the weakness of the area between the rivers Sarre and Lauter, three gros ouvrages were proposed, to be completed between 1929 and 1933.

[1][4] The town of Rohrbach-lès-Bitche is located on a shelf between the Vosges mountains and the valley of the Sarre, tunneled beneath by plaster mines.

The constructed portions of Rohrbach are on the edge of an escarpment, while most of the proposed additional blocks, as well as the entries, were to be located several hundred meters to the rear in a ravine, tunneled under the village.

[9] The Casernement de Bining provided peacetime above-ground barracks and support services to Rohrbach and other positions in the area.

On the 16th the Germans sent large formations through the gap they had exploited in the Sarre valley, moving behind the Maginot Line.

[1][12] By 1951 work was proceeding on renovation of many of the northeastern ouvrages, including Rohrbach, with the aim of restoring their combat capability to block a potential advance by the Warsaw Pact.
