What is Castle?

Castle

Quick Answer

A castle is a large fortified building or group of buildings that was used in medieval times for defense and residence. They often featured thick walls, towers, and a moat to protect against invaders.

Overview

Castles were built during the medieval period, primarily from the 9th to the 15th centuries, as a means of defense and as a home for nobility. They were strategically placed on high ground or near water to provide a tactical advantage against attackers. The design of a castle typically included features such as thick stone walls, a drawbridge, and towers for lookout and defense. Inside a castle, there were living quarters, stables, and storage areas, making it a self-sufficient community. Castles also served as administrative centers where local lords governed their lands and collected taxes. A well-known example is the Tower of London, which has served various roles throughout its history, including a royal palace and a prison. Castles played a crucial role in medieval society by providing security and establishing the power of feudal lords. They were symbols of wealth and influence, often attracting artisans and merchants who wanted to live and work near the nobility. As warfare evolved, the function of castles changed, leading to the development of new military architecture.
