Besançon is the old capital of Franche-Comté (traditional province of Eastern France). The fortress is built on a rock in the form of a tortoiseshell, 118 meters above the Doubs River. Images of the archeological square, Castan. Images of the town of Beure and Baume-les-dames. The Condé basins on the Doubs is where Marquis Jouffroy d'Abbans first tried out steam navigation. Images of the thermal baths of Guyon-les-Bains. In solitude and serenity, Audeux follows its rather impetuous course. Images of the fan-shaped Grâce Dieu waterfall.
