Montluçon (; ) is a commune in central France on the river Cher. It is the largest commune in the Allier department, although the department's prefecture is located in the smaller town of Moulins. Its inhabitants are known as Montluçonnais. The town is in the traditional province of Bourbonnais and was part of the mediaeval duchy of Bourbon. Geography Montluçon is located in the northwest of the Allier department near the frontier of the Centre-Val de Loire and Nouvelle-Aquitaine regions. Montluçon is linked with surrounding regions and towns via four main road axes, plus the highway A71 from Orléans to Clermont-Ferrand; through a railway linking in the North Vierzon then Paris (3-5h). Formerly the canal de Berry linked Montluçon towards the north. Montluçon is south of Bourges, from Paris, from Clermont-Ferrand, (3h) from Lyon, (2h) from Limoges and from the Atlantic coast. Montluçon is close to the Méridienne verte (an architectural project marking the Paris meridian) and to the Greenwich meridian. Montluçon is also close to the geographic centre of Metropolitan France. History Early history Montluçon was built in the Middle Ages. The first mention of a place called Monte Lucii (Mont de Lucius) dates from the eleventh century. Guillaume, son of Archambaud IV of Bourbon, built the castle in a defensible position on a small rocky hill on a bend in the river Cher. The town, which formed part of the duchy of Bourbon, was taken by the English in 1171, and by Philip Augustus in 1181; the English were finally driven out in the 14th century. In the 14th century, Louis II de Bourbon re-built the castle and walls. Montluçon and other Bourbon lands reverted to the French crown in 1529, and Henry IV further improved the defenses. Montluçon became the administrative seat of the area in 1791, then entered the industrial era thanks to the presence of coalpits distant in Commentry, the Canal de Berry in 1830 and the railway in 1864. These transport links allowed the import of ore and export of coal, wood and manufactured goods. The population grew from 5000 inhabitants in 1830 to 50 000 in 1950.
