The fortifications at this site have undergone many changes. In the Middle Ages, there was a castle on this site, Chastel Belin, which was apparently destroyed in the 17th century. From 1674, Vauban had the Château Belin built with further fortifications, which were, however, razed to the ground by the Austrians at the beginning of the 19th century and rebuilt in 1828. In 1871, during the Franco-Prussian War, the city capitulated to a numerically superior enemy, but the Belin and Saint-André forts did not surrender and held the strategically important position. Today it is privately owned and is apparently being renovated.

In a rural setting, the Saint-Joseph chapel with its lava-covered roof is located within the territory of the commune of Salins-les-Bains even if it is right next to the hamlet of La Chaux-sur-Clucy.

Iconic 17th century chapel built following a vow made by the population to thank the Virgin Mary for protecting the inhabitants from epidemics and during the Thirty Years' War. It has an oval plan and is surmounted by a recently renovated dome with glazed roof tiles, a lantern tower and a bell tower. https://www.coeurdujura-tourisme.com/

The ascent to the cross is car-friendly and has steps. The GR59 may have been rerouted in the meantime, but a detour here is definitely justified. The paths on Mt Poupet are well signposted and the summit cross is highly recommended.

The views are particularly wonderful at the many paraglider take-off points on Mont Poupet. However, the location of this highlight is surrounded by dense forest and an antenna, so visiting this point is only worthwhile if you follow the path a little further north.

It is very interesting to visit the saltworks. The underground part of the tour is only possible with a guide. It is best to be there early in the morning for the sightseeing, otherwise there will be too many people there. The saltworks is a world cultural heritage site.
