The historical structure that served as a symbol of power in medieval Europe is the castle. Castles arose during the feudal period as fortified residences for nobility, serving both as military defense and as administrative centers for the surrounding lands. Their architecture, featuring thick walls, towers, and moats, was designed to withstand attacks and assert the lord's dominance over the region. Castles became symbols of social status and power, signifying the wealth and influence of their inhabitants. Over time, they evolved into complex environments, featuring living quarters, chapels, and storied halls, ultimately representing the strength and stability of feudal governance.
