Ancient castles are large fortified structures built during the Middle Ages, primarily in Europe. They served as residences for nobility and as military strongholds. Castles were designed with thick walls, towers, and moats to protect against invasions. Many castles, like Neuschwanstein Castle in Germany, showcase impressive architecture and historical significance. Over time, many ancient castles have been preserved or restored, attracting tourists and historians alike. They often feature grand halls, dungeons, and battlements, providing insight into medieval life. Notable examples include Edinburgh Castle in Scotland and Château de Chambord in France, each reflecting the culture and history of their regions.
