A battlement in defensive architecture, such as that of city walls or castles, comprises a parapet (i.e., a defensive low wall between chest-height and head-height), in which gaps or indentations, which are often rectangular, occur at intervals to allow for the launch of arrows or other projectiles from within the defences. These gaps are termed "crenels" (also known as carnels, or embrasures), and a wall or building with them is called crenellated; alternative (older) terms are castellated and embattled. The act of adding crenels to a previously unbroken parapet is termed crenellation.
The function of battlements in war is to protect the defenders by giving them something to hide behind, from which they can pop out to launch their own missiles. A defensive building might be designed and built with battlements, or a manor house might be fortified by adding battlements, where no parapet previously existed, or cutting crenellations into its existing parapet wall. A distinctive feature of late medieval English church architecture is to crenellate the tops of church towers, and often the tops of lower walls. These are essentially decorative rather than functional, as are many examples on secular buildings.
The solid widths between the crenels are called merlons. Battlements on walls have protected walkways (chemin de ronde) behind them. On tower or building tops, the (often flat) roof is used as the protected fighting platform.
The term originated in about the 14th century from the Old French word batailler, "to fortify with batailles" (fixed or movable turrets of defence). The word crenel derives from the ancient French cren (modern French cran), Latin crena, meaning a notch, mortice or other gap cut out often to receive another element or fixing; see also crenation. The modern French word for crenel is créneau, also used to describe a gap of any kind, for example a parking space at the side of the road between two cars, interval between groups of marching troops or a timeslot in a broadcast.[1]
In medieval England and Wales a licence to crenellate granted the holder permission to fortify their property. Such licences were granted by the king, and by the rulers of the counties palatine within their jurisdictions, e.g. by the Bishops of Durham and the Earls of Chester and after 1351 by the Dukes of Lancaster. The castles in England vastly outnumber the licences to crenellate.[2] Royal pardons were obtainable, on the payment of an arbitrarily determined fine, by a person who had fortified without licence. The surviving records of such licences, generally issued by letters patent, provide valuable evidence for the dating of ancient buildings. A list of licences issued by the English Crown between the 12th and 16th centuries was compiled by Turner & Parker and expanded and corrected by Philip Davis and published in The Castle Studies Group Journal.[3]
There has been academic debate over the purpose of licensing. The view of military-focused historians is that licensing restricted the number of fortifications that could be used against a royal army. The modern view, proposed notably by Charles Coulson, is that battlements became an architectural status-symbol much sought after by the socially ambitious, in Coulson's words: "Licences to crenellate were mainly symbolic representations of lordly status: castellation was the architectural expression of noble rank".[4][3] They indicated to the observer that the grantee had obtained "royal recognition, acknowledgment and compliment".[5][3] They could however provide a basic deterrent against wandering bands of thieves, and it is suggested that the function of battlements was comparable to the modern practice of householders fitting highly visible CC-TV and burglar alarms, often merely dummies. The crown usually did not charge for the granting of such licences, but occasionally charged a fee of about half a mark.[3]
Battlements may be stepped out to overhang the wall below, and may have openings at their bases between the supporting corbels, through which stones or burning objects could be dropped onto attackers or besiegers; these are known as machicolations.

The Romans used low wooden pinnacles for their first aggeres (terrepleins). In the battlements of Pompeii, additional protection derived from small internal buttresses or spur walls, against which the defender might stand so as to gain complete protection on one side.
In Muslim and African fortifications, the merlons often were rounded. The battlements of the Arabs had a more decorative and varied character, and were continued from the 13th century onwards not so much for defensive purposes as for a crowning feature to the walls. They serve a function similar to the cresting found in the Spanish Renaissance architecture.
"Irish" crenellations are a distinctive form that appeared in Ireland between the 14th and 17th centuries. These were battlements of a "stepped" form, with each merlon shaped like an inverted 'T'.[7][8]<

European architects persistently used battlements as a purely decorative feature throughout the Decorated and Perpendicular periods of Gothic architecture. They not only occur on parapets but on the transoms of windows and on the tie-beams of roofs and on screens, and even on Tudor chimney-pots. A further decorative treatment appears in the elaborate paneling of the merlons and that portion of the parapet walls rising above the cornice, by the introduction of quatrefoils and other conventional forms filled with foliage and shield.
