Differdange (French pronunciation: [difɛʁdɑ̃ʒ]; Luxembourgish: Déifferdeng [ˈdɜɪ̯fɐdeŋ] ⓘ or locally Déifferdang [ˈdɜɪ̯fɐdɑŋ]; German: Differdingen [ˈdɪfɐdɪŋən]) is a commune with town status in south-western Luxembourg, 27 kilometres (17 mi) west from the country's capital.

Differdange is an industrial town that was home to much of Luxembourg's steel production, much of its development occurred during its heyday.

The era of the Cistercian cathedrals and abbeys was in full swing during the thirteenth century and Differdange did not deviate from this pattern.

Subsequently, women from the Lorraine region of France and the present province of Luxembourg in Wallonia also made their vows at Differdange.

However, it was during the French invasion of Luxembourg that the abbey and the town experienced real raids and innumerable rampages.

Although it has no known origin since all traced manuscripts have disappeared, squire listed was Wilhelm de Differdange, named in documents dating from 1310.

In 1794, the French Revolutionary Army committed atrocities in Differdange and slaughtered many unarmed civilians before pillaging and burning the city.
