A Castellan is a person responsible for the management and defense of a castle or fortification. This role was especially important during the medieval period when castles served as both residences and military strongholds. The castellan oversaw the daily operations, including the maintenance of the castle, the management of supplies, and the organization of the garrison. In addition to administrative duties, the castellan played a crucial role in the castle's defense. They were often in charge of training the soldiers and ensuring that the castle was prepared for any potential attacks. The position of castellan was typically appointed by a lord or noble, such as a duke or king.
