Perched dramatically on a limestone promontory, the walled city of Langres is a fortress of immense historical stature in the Haute-Marne department. Unscathed by time, the town is completely encircled by eight kilometers of defensive ramparts, punctuated by twelve sturdy towers and seven imposing gates, offering visitors a spectacular elevated walkway with unbroken panoramic views over the Marne Valley and the distant Vosges. Langres is fiercely proud of its intellectual heritage as the birthplace of the great Enlightenment philosopher Denis Diderot, to whom a dedicated museum in the town center pays homage. The narrow, cobbled streets within the walls are lined with elegant Renaissance mansions and center around the Romanesque-Gothic Saint-Mammès Cathedral, characterized by its beautifully austere stone façade. No visit to this high-altitude stronghold is complete without tasting the eponymous Langres cheese, a pungent, washed-rind delicacy traditionally enjoyed with a splash of local Marc de Bourgogne poured into its characteristic hollow top.
