Castle construction refers to the building of fortified structures, primarily during the Middle Ages in Europe. These castles were designed for defense and often featured thick stone walls, towers, and moats. The layout typically included living quarters, storage areas, and a chapel, all organized around a central courtyard. The materials used in castle construction varied by region but commonly included limestone, granite, and wood. Skilled craftsmen, such as masons and carpenters, played crucial roles in the building process. Over time, castles evolved in design, reflecting changes in military technology and architectural styles.
