What is a castle?

Castles are large fortified structures that were primarily built during the Middle Ages by nobility or royalty for defense, residence, and administration. They typically feature thick walls, towers, battlements, and sometimes moats, designed to protect inhabitants from attacks. Castles served not only as military strongholds but also as symbols of power and authority. Over time, many castles have become historical monuments and tourist attractions, showcasing medieval architecture and history.
