context_page_description: A castle is a type of fortified structure built during the Middle Ages predominantly by the nobility or royalty and by military orders. Scholars debate the scope of the word castle, but usually consider it to be the private fortified residence of a lord or noble. This is distinct from a palace, which is not fortified; from a fortress, which was not always a residence for royalty or nobility; and from a fortified settlement, which was a public defence – though there are many similarities among these types of construction. Usage of the term has varied over time and has been applied to structures as diverse as hill forts and country houses. Over the approximately 900 years that castles were built, they took on a great many forms with many different features, although some, such as curtain walls, arrowslits, and portcullises, were commonplace.
  European-style castles originated in the 9th and 10th centuries, after the fall of the Carolingian Empire resulted in its territory being divided among individual lords and princes.
context_section_description: Castle is sometimes used as a catch-all term for all kinds of fortifications and, as a result, has been misapplied in the technical sense. An example of this is Maiden Castle which, despite the name, is an Iron Age hill fort which had a very different origin and purpose.
  Although "castle" has not become a generic term for a manor house (like château in French and Schloss in German), many manor houses contain "castle" in their name while having few if any of the architectural characteristics, usually as their owners liked to maintain a link to the past and felt the term "castle" was a masculine expression of their power. In scholarship the castle, as defined above, is generally accepted as a coherent concept, originating in Europe and later spreading to parts of the Middle East, where they were introduced by European Crusaders. This coherent group shared a common origin, dealt with a particular mode of warfare, and exchanged influences.
  In different areas of the world, analogous structures shared features of fortification and other defining characteristics associated with the concept of a castle, though they originated in different periods and circumstances and experienced differing evolutions and influences. For example, shiro in Japan, described as castles by historian Stephen Turnbull, underwent "a completely different developmental history, were built in a completely different way and were designed to withstand attacks of a completely different nature". While European castles built from the late 12th and early 13th century onwards were generally stone, shiro were predominantly timber buildings into the 16th century.
  By the 16th century, when Japanese and European cultures met, fortification in Europe had moved beyond castles and relied on innovations such as the Italian trace italienne and star forts. Forts in India present a similar case; when they were encountered by the British in the 17th century, castles in Europe had generally fallen out of use militarily. Like shiro, the Indian forts, durga or durg in Sanskrit, shared features with castles in Europe such as acting as a domicile for a lord as well as being fortifications. They too developed differently from the structures known as castles that had their origins in Europe.
