Some ruins on an eminence above the town mark the site of a château of the dukes of Burgundy. Nearby stands the church of St Vorles of the 10th century, but with many additions of later date; it contains a sculptured Holy Sepulchre of the 16th century and a number of frescoes. In a fine park stands a modern château built by Marshal Marmont, duke of Ragusa, born at Châtillon in 1774. It was burnt in 1871, and subsequently rebuilt. Châtillon anciently consisted of two parts, Chaumont, belonging to the duchy of Burgundy, and Bourg, ruled by the bishop of Langres; it did not coalesce into one town until the end of the 16th century. It was taken by the English in 1360 and by Louis XI in 1475, during his struggle with Charles the Bold. Châtillon was one of the first cities to adhere to the League, but suffered severely from the oppression of its garrisons and governors, and in 1595 made voluntary submission to Henry IV. It is associated with the abortive conference of 1814 between the representatives of Napoleon and the Allies. During World War II the German garrison were forced to withdraw after a successful operation by the Special Air Service operating in the nearby forest in late August 1944.
