The Château de Morimont () is a ruined castle in the Alsace region of France, in the commune of Oberlarg in the Haut-Rhin département. It is 40 km southwest of Mulhouse and 45 km west of the Swiss city of Basel. History The first documented mention of the castle is from 1271, when the Count of Ferrette made an oblation to the bishop of Basel. It was occupied by, and takes its name from, the Morimont family, vassals of the Ferrettes, and later the Habsburgs. A war with Basel and the Swiss led to the castle's destruction some time between 1445 and 1468. It was rebuilt by the Morimonts in the 15th and 16th centuries with seven artillery towers. In 1582 they sold it to the Counts of Ortenbourg Salamanque who kept it until the Thirty Years' War, during which it was destroyed by French troops in 1637. In 1641, Louis XIV gave it and the manor to the Vignacourts, who stayed until the French Revolution. It subsequently belonged to Jean Bruat, then Aaron Meyer, and, from 1870, the Viellard family. Architecture Built on a rocky east-west crest, the castle dominates the route between Oberlag and Levoncourt. It is constructed from Jurassic limestone with a lime mortar. The northern building, measuring 51 by 7.5 m (~170 by 25 ft), has an underground semicircular vaulted cellar running its full length, and the remains of two spiral staircases. The southern building consists of a polygonal staircase tower and the remains of pointed-arch vaulting and a fireplace. The tower in the northwest corner has oven-shaped vaulting. The southern artillery tower has three vaulted casemates whose cannon openings are set to fire horizontally, with one covering the entrance. The northeast tower, built in 1515, has been restored, and the present entrance to the cellar through the curtain wall is not original. The oldest part of the present castle — a U-shaped tower in the southern corner — dates from the 13th or 14th century. Referred to by most authors as a keep, it was built onto the bare rock and provided the first residential quarters. The southwest Schlossturm Tower dates from the 15th century, as do part of the west and south curtain walls. In the north, the great hall of 1552, on the probable site of the former lower courtyard, is flanked by two large artillery towers; the northeast tower, dated 1515, carries
