a town of France, in the department of Jura, picturesquely placed at the head of a beautiful valley, in a gorge between two mountains, 26 miles N.E. of Lons-le-Saunier. It is encircled by walls, and defended by two forts on adjacent heights. Most of the buildings are new and substantial, as the town was almost wholly destroyed by fire in 1825. There are many churches, a large college theatre, barracks, and jail. But the largest establishment in the town are the salt works ("Saline Royales"), which give the place its name. These are about 300 yards long by 100 broad, and are inclosed with an embattled wall. The salt is obtained from springs, which are supposed to have been used as early as the time of the Romans. Brandy, leather, and sulphate of soda are also made here; and there is some trade in wine, brandy, cheese, honey, salt, timber, gypsum, &c. Pop. 7481.
