"The Citadel of Besan\u00E7on in Franche-Comt\u00E9, France, is one of the finest masterpieces of military architecture designed by S\u00E9bastien Le Prestre de Vauban. The Citadel occupies eleven hectares on Mount Saint-Etienne, one of the seven hills that protect Besan\u00E7on, the capital of Franche-Comt\u00E9. Mount Saint-Etienne occupies the neck of an oxbow formed by the river Doubs, giving the site a strategic importance that Julius Caesar recognised as early as 58 BC."@en .
