The international border between the modern states of France and Germany has a length of 450 km (280 mi).

The border then turns westward until it reaches the tripoint between France, Germany and Luxembourg.

The border changed again in 1941 when Nazi Germany de facto annexed the region (without international legal recognition, or treaty).

The current border was re-established after the defeat of Nazi Germany in World War II.

It passes Saarbrücken, Petite-Rosselle, Freyming-Merlebach, Creutzwald (where it follows the Bist for a short stretch), Überherrn, and meets the E29 before it terminates at the French-Luxembourgish-German tripoint on the Moselle, near the village of Schengen, Luxembourg (49°27′36″N 6°22′08″E / 49.460°N 6.369°E / 49.460; 6.369; chosen as the symbolic site for the signing of the Schengen Agreement between France, Germany, and the Benelux countries in 1985).
