Château de Mâlain is an 11th-century ducal stronghold located on a rocky ridge in Burgundy's Côte-d'Or region, redesigned significantly in the 16th century. The castle holds unique historical importance as a witness to medieval Burgundian feudal dynamics, having been occupied by influential families including the Sombernons, Montagues, and Mâlains who played roles at the royal court. A remarkable architectural feature is the literal division of the castle into two separate parts, resulting from a 1419 inheritance dispute between two nieces of Pierre de Montagu. For over forty years, the Groupe Archéologique Mesmontois has gradually restored the castle through extensive renovation and archaeological excavations, bringing this important regional monument back to life for visitors.
