Lörrach German pronunciation: [ˈlœrax] is a city in southwest Germany, in the valley of the Wiese, close to the French and the Swiss borders. It is the capital of the district of Lörrach in Baden-Württemberg. The largest industry is the Milka chocolate factory.
In 1973 part of the district Müllheim and small parts of the district Säckingen were added to the district, which enlarged the district by about 25% to the current size.
