Esch-sur-Alzette (, or
Esch-an-der-Alzig, ) is a
commune with
city status in south-western
Luxembourg. It is the country's
second city, and its
second-most populous commune, with a population of 33,286 inhabitants. It lies in the south-west of the country, on the border with France. The town is usually referred to just as
Esch, but there is also a village and commune further north named
Esch-sur-Sûre from which to distinguish it. It lies in the
valley of the
Alzette, which flows through the town. The capital,
Luxembourg City, is roughly to the north-east.
