Esch-sur-Alzette (Luxembourgish: Esch-Uelzecht, German: Esch-an-der-Alzette or Esch-an-der-Alzig, French: Esch-sur-Alzette) is a commune with town 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, is roughly 15 km (9.3 mi) to the north-east.
