From Clamecy the highroad crosses the Bazois to Chateau Chinon in the Nivernais. The name leads one to imagine much, but of chateaux it has none, though its nomenclature was derived from the emplacement of an ancient _oppidum gaulois_, a _castrum gallo-romain_ and later a feudal chateau. The road on to Burgundy lies to the southwest via the Avallonnais, or, leaving the watershed of the Yonne for that of the upper Seine, via Tonnerre and Châtillon-sur-Seine lying to the eastward of Auxerre. CHAPTER III AVALLON, VEZELAY AND CHASTELLUX Avallon owes its origin to the construction of a chateau-fort. It was built by Robert-le-Pieux, the son of Hugues Capet, in the tenth century. Little by little the fortress has crumbled and very nearly disappeared. All that remains are the foundation walls on what is locally called the Rocher d'Avallon, virtually the pedestal upon which sits the present city. Avallon, like neighbouring Semur and Vezelay, sits snugly and proudly behind its rampart of nature's ravines and gorges, a series of military defences ready-made which on more than one occasion in mediæval times served their purpose well. It was in the old Chateau d'Avallon that Jacques d'Epailly, called "Forte Épice," was giving a great ball when Philippe-le-Bon beseiged the city. Jacques treated the inhabitants with the utmost disrespect, even the ladies, and secretly quitted the ball just before the city troops surrendered. History says that the weak-hearted gallant sold out to the enemy and saved himself by the back door, and in spite of no documentary evidence to this effect the long arm of coincidence points to the dastardly act in an almost unmistakable manner. Near Avallon are still to be seen extensive Roman remains. A Roman camp, the Camp des Alleux, celebrated in Gaulish and Roman history, was here, and the old Roman road between Lyons and Boulogne in Belgica Secundus passed near by. It is not so much with reference to Avallon itself, quaint and picturesque as the city is, that one's interest lies hereabouts. More particularly it is in the neighbouring chateaux of Chastellux and Montréal.
