As illustrated by its period houses and buildings, the City of Art and History of Montbéliard boasts beautiful architectural heritage. The places of interest there include:
- The castle of the dukes of Wurtemberg, flanked by two Renaissance towers, which is home to a museum dedicated to archaeology, history and natural history;
- The Saint-Pierre square and its monuments, such as the Saint-Martin temple dating from the beginning of the 17th century (oldest reformed church in France), the town hall, the Forstner house, and the Beurnier-Rossel mansion and its Art and History museum;
- The very well-preserved covered market hall dating from the 16th century and the pierre à poissons, a stone slab on which fish used to be sold on market days;
- The pedestrian streets lined with colourfully-fronted houses...
In Sochaux, the factories of the famous French car manufacturer Peugeot, as well as the Peugeot Adventure museum, can be visited.
