For a long time Esch was a small farming village in the valley of the Uelzecht river. This changed when important amounts of iron ore were found in the area in the 1850s. With the development of the mines and the steel industry the town's population multiplied tenfold in a couple of decades. In 1911 the steel- and iron-producing company ARBED was founded. The development of the steel industry, especially in the south of the country, provided Luxembourg with sustained economic growth during the second half of the 19th century.
