The History and Significance of Crenelles in Medieval Fortifications

Crenelle (pronounced "cray-nel") is a type of fortification wall that was commonly used in medieval castles and other fortified structures. It consists of a series of recesses or niches, called "crenelles," that are cut into the top of the wall. These crenelles are typically rectangular in shape and are designed to provide cover for defenders while they fire on attackers.

Crenelles were often used in conjunction with other types of fortifications, such as moats and drawbridges, to provide additional protection and make it more difficult for attackers to breach the walls of a castle or other fortified structure. They were also sometimes used to provide ventilation and light to the interior of the structure.

The term "crenelle" is derived from the Latin word "crenella," which means "small trench." It is still used today in architectural and historical contexts to describe this type of fortification wall.
