Saline Royale and Grotto Osselle
Listed as a UNESCO world heritage site, Royal Saltworks at Arc-et-Senans is a historic monument of great importance. A unique testimony of the industrial architecture of the Enlightenment era, this set of buildings has been painstakingly restored, in 60 years by its owner, the Doubs department.
Several museums and a zoo over an area of 11 ha. The citadel overlooks over 100 meters the old town of Besançon enclosed in a magnificent loop formed by a meander of the Doubs. An impressively restored fortress, the Citadel is an one of its kind cultural and tourist landmark, which invites you to experience history and life.
The Loue, 126 km long, is a resurgence of the Doubs River. It dugs her bed in the limestone of the Jura plateau before joining the Doubs downstream of Dole. It is between the source of the Loue and Ornans, the capital of the high valley of the Loue that the valley is of most interest. In some 20 km, the river drops 229 meters. It sinks to the bottom of often wooded gorges. The panorama from several viewpoints is impressive. Traditional villages are located along the course of the Loue.
Small Franche-Comté city of great character, known for its thermal baths, its potters and pottery stores. You can also visit the saltworks, a landmark of industrial heritage, with its hydraulic system of the nineteenth century, still in operation...
For the beauty of its natural setting, the variety of its crystals and colours, for its geological phenomena and historical and prehistoric treasures, the Osselle cave has its place among the world’s most amazing caves.
Two open circuits of 1200 and 1500 metres, allowing the public to observe
and understand the formation of various karstic phenomena in our region:
limestone pavements, pit caves, sinkholes, caves... not to mention the
discovery of the fauna and flora of the limestone environment.
With its hanging houses, narrow gardens, bridges that span it, its ochre and blue colours that it reflects, the Loue holds a large share in the fame of ORNANS as the "Little Venice of Franche-Comté".
The city is adherent to the "Small cities of Franche-Comté of Charactr ".
