Castles in Europe are fortified structures built primarily during the Middle Ages. They served as residences for nobility and as military strongholds. Many castles feature thick stone walls, towers, and moats, designed for defense against invaders. Notable examples include Neuschwanstein Castle in Germany and Edinburgh Castle in Scotland. Today, these castles are popular tourist attractions, showcasing rich history and architecture. They often host events, festivals, and reenactments, allowing visitors to experience medieval life. Some castles, like Château de Chambord in France, are also recognized for their stunning gardens and surrounding landscapes, enhancing their appeal.
