chatelain

A chatelain was historically the keeper or governor of a castle. The term derives from the Old French word "chastelain," meaning "castle warden." This individual held significant responsibility, often acting as the lord's representative in his absence. The chatelain's duties varied depending on the size and importance of the castle, but generally included overseeing the castle's defenses, managing its stores and provisions, maintaining order within its walls, and administering justice for minor offenses.

In some instances, a chatelain could be a powerful figure, commanding a garrison of soldiers and holding considerable local authority. They were typically of noble birth, though sometimes appointed from among trusted knights or administrators. The role was distinct from that of the castle's owner, who might be a king, duke, or other high-ranking noble. The chatelain's position was crucial for the effective functioning and security of a medieval fortification. The concept of the chatelain largely faded with the decline of castles as primary residences and military strongholds, replaced by more modern administrative structures.
