🏰Medieval castles can be categorized into three main types: enclosed castles, linked castles, and unwalled castles.
🔒Enclosed castles consist of a keep that is surrounded by a defensive wall, holding historical examples like the Tower of London.
🔗Linked castles have primary fortified buildings that are either part of the outer walls or connected by towers, such as Conway Castle.
🚫Unwalled castles are fortified structures without outer walls, including tower houses like Clackmannan Tower.
🏰Other subcategories of castle types include towered castles and fortified manor houses.
