Lachaussée (pronounced as /fr/) is a commune in the Meuse department in Grand Est in north-eastern France. In January 1973, it absorbed the former communes Haumont-lès-Lachaussée and Hadonville-lès-Lachaussée.[2]
The village of Lachaussée lies on the south-eastern rim of a huge pond named Étang de Lachaussée, which was created during the Middle Ages from a marsh area and then devoted to pisciculture.
