Turrets are small towers that are often part of a larger structure, such as a castle or a building. They can serve various purposes, including providing a vantage point for defense or observation. In medieval architecture, turrets were commonly used to enhance the aesthetic appeal of castles and fortifications. In modern contexts, turrets can also refer to rotating weapon platforms found on military vehicles or ships. These turrets allow for the mounting of guns or missiles, enabling them to aim and fire at targets from different angles without moving the entire vehicle.
