Origin and history

The tower of the Motte-Forte d'Arnay-le-Duc is the last vestige of a medieval castle built on an ancient Gallo-Roman castrum. From the early Middle Ages, a first castral motte occupied the site, before the castle was ceded in 1216 to the Duke of Burgundy by Hughes d'Arnay. This strategic site, located at the crossroads of Roman roads, became a major local issue, especially after 1361, when the inhabitants of Arnay-le-Duc inherited it with the obligation to maintain and defend it.

The present tower, built in 1529, marked a period of defensive reinforcement before the disturbances of the religious wars. After the Battle of Arnay in 1570, the castle was gradually dismantled from 1593, its stones being used for local constructions. Only the tower, transformed into a prison, city hall and library until the Revolution, escaped destruction. Its typical architecture — three crenellated floors crowned with machicolis — reflects the military techniques of the time.

Ranked a Historic Monument in 1921, the tower today symbolizes the Burgundian medieval heritage. Its history combines seigneurial power, religious conflicts and civil reuse, illustrating the evolution of the uses of castles in Burgundy. Local excavations and archives, such as Didier Godard (2009), confirm his central role in the history of Arnay-le-Duc, from antiquity to modern times.
