Close to Germany and Switzerland, with which it is closely linked, Mulhouse is an astonishing city that is very industrial! For a long time a city-state and then an independent republic, it was only (voluntarily) attached to France in 1798, before quickly becoming one of the first industrial centers of Europe, a period of which it still retains many traces today. A Mulhouse tourist guide will tell you all about it: after the spinning mills, the mining industry and the electrical industry, it was the turn of the automobile industry to develop. Today, the PSA Peugeot-Citroën group is the largest employer in the region with its plant in Sausheim. If your visit is to last only a few hours, concentrate on the Place de la Réunion in the historic city center. Must-sees are the town hall (which houses the Historical Museum), the Saint-Etienne temple, some beautiful houses, such as the Mieg house, the Lys pharmacy, as well as the old fortifications and their various towers. If you have several days or already know the city, opt for a visit to one of the main museums, such as the Cité de l'automobile, the Cité du train or the EDF-Electropolis museum, for example. You can also visit the PSA Peugeot-Citroën assembly lines.
