The Château de Mehun-sur-Yèvre is a castle in the town of Mehun-sur-Yèvre in the départment of Cher, France.The castle is classified as a Monument historique since 1840.
The castle is built on a trapezoid plan, and originally had a tall cylindrical tower at each corner and a rectangular tower in the middle of one of the long sides. An entrance was formed in the wall between two of the towers. One tower (12m diameter), was much larger than the others (8m), and served as the keep or donjon. The keep and the west tower still stand to their full height, each capped with intricate defensive machicolations.
