creneler
Creneler is a term used in architecture and fortification to describe the alternating upright blocks and gaps along the top of a wall or parapet. These features are collectively known as battlements or merlons and crenels, respectively. The upright blocks, called merlons, were designed to provide cover for defenders, while the gaps, called crenels, allowed them to shoot arrows or other projectiles at attackers. Crenellations are a prominent feature of medieval castles and defensive structures, serving both a practical defensive purpose and a symbolic representation of power and military strength. The development of crenellations can be traced back to ancient fortifications, but they became particularly widespread and elaborate during the Middle Ages. The design of crenellations varied depending on the specific architectural style, the intended use of the structure, and the available resources. In addition to their defensive function, crenellations also played a role in the aesthetics of buildings, adding visual interest and a sense of grandeur to their upper reaches. The term creneler itself refers to the act of adding crenellations to a wall or structure.
