Before the 12th century, the lords of Cléron succeeded the lords of Scey to control the crossing of the River Loue by a wooden bridge on the main « Route du sel » ("salt road") of Franche-Comté, the road linking Besançon to Salins-les-Bains and assuring the prosperity of the region in the Middle Ages.[1]
The castle was heavily remodelled in the 18th century while preserving its Middle Ages defences - keep, machicolations, arrowslits and murder-holes. It is flanked by a square tower, the Clock Tower, from the 19th century.[1]
