[1] The gros ouvrage[nb 1] is of the typical fort palmé ("palm-shaped") form for a large position.

Anzeling was served by a 60 cm-gauge narrow-gauge railway, which enters at the munitions entrance and runs all the way out through the galleries to the combat blocks.

[7] Anzeling also features a mixed-arms turret in Block 9, equipped with a machine gun and a 50mm grenade launcher that could fire when retracted.

Called the fosse aux ours, or "bear pit", the ventilation block was large enough to merit its own mixed-arms turret.

[17] The nearby Casernement de Bockange provided peacetime above-ground barracks and support services to Anzeling and other positions in the area.

Anzeling fired on German forces on the surface of ouvrage Bousse, causing some damage to the installation.

[20] During the night of 17–18 June, German troops appear on the surface of Anzeling blocks 1 and 3 and to the rear of the ouvrage.

During the following days the minefields surrounding the ouvrage were removed and the commandant negotiated terms for a surrender.

[23] Following World War II, interest revived in the use of the Maginot Line to defend against a possible Soviet advance through southern Germany.

Funding was not forthcoming for upgrades to heavier arms, and work was limited to restoration of systems and improvements to existing armament.

By 1956, Anzeling had been designated part of the Mòle de Boulay, a strongpoint in the northeastern defenses against Soviet attack.
