A bartizan is a fortified architectural feature found in medieval castles and fortresses. It typically takes the form of a small, turret-like structure that projects from the corners or sides of a castle's walls. Bartizans are characterized by their defensive function, providing an elevated vantage point for observation and defense, often equipped with loopholes or openings for archers or artillery. These structures serve as both practical defensive elements and decorative features, adding to the grandeur and imposing nature of the castle's overall design.
