Hugh of Chalon (French: Hugues de Chalon; c. 975 – 4 November 1039) was the Count of Chalon and Bishop of Auxerre.
Hugh was the only son of Lambert of Chalon and his wife Adela (Adelais, Adelaide), and was made a canon of the Cathédrale Saint-Nazaire in Autun.
Upon the death of his father in 978, Hugh became Count of Chalon. Hugh's sister or rather half-sister Gerberga was married to Henry I, Duke of Burgundy. In 999, at the request of Duke Henry, Hugh was named Bishop of Auxerre.
The Benedictine house at Paray-le-Monial had been founded in 973 by Hugh's parents. By 999 it was in need of reform, and Count Hugh gave it to Cluny as a priory.
The large crypt of the Cathédrale Saint-Étienne d'Auxerre was built between 1023 and 1030,[1] when he rebuilt the earlier Romanesque structure. The crypt was immense, with three naves and six traverses. It also featured a new architectural element, a disambulatory, a passage which permitted pilgrims to circulate and visit the tombs in the crypt without disturbing the religious services attended by the clergy.[2]
Some time between 1023 and 1036, the bishop made a pilgrimage to Jerusalem.[3]
His successor was his sororal nephew, Count Theobald of Chalon, son of Hugh's sister Matilda (French: Mathilde).
