A castle part is a term used to describe the various components of a castle. The most common castle parts are the DUNGEON (7 letters), TOWER (5 letters), TURRET (6 letters), PARAPET (7 letters) and KEEP (4 letters). The DUNGEON is typically located underground and was used as a prison or storage area. The TOWER is a tall structure that is usually the tallest part of the castle and was used for defense and observation. The TURRET is a small TOWER that is usually located on the corners of the castle walls and was used for defense. The PARAPET is a wall-like structure that is built along the top of the castle walls and was used for defense. Finally, the KEEP is a large, fortified TOWER that is located at the center of the castle and was used as a last line of defense.
