Battlement

A pattern of offensive structure focused of structure of actions of defensive capability:

A battlement in defensive architecture, such as that of city walls or castles, comprises a parapet (i.e. a defensive low wall betweem chest-height and head-height), in which rectangular gaps or indentations occur at intervals to allow for the discharge of arrows or other missiles from within the defences. These gaps are termed "crenels" (also known as carnels, embrasures, or wheelers), and the building operation of embattling a previously unbroken parapet is termed crenellation. Thus 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. The solid widths between the crenels are called merlons (also cops or kneelers). A wall with battlements is said to be crenelated or embattled. Battlements often have protected walkways (chemin de ronde) behind them.

Etymology

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), meaning a notch, mortice or other gap cut out often to receive another element or fixing. The modern French word for crenel is creneau, 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]

Licence to crenellate

In mediaeval England a royal licence was required before an owner could fortify his house by the cutting-out of crenellations, or building up of battlements, known as a "licence to crenellate". This restricted the number of fortifications which could be used against a royal army. The surviving records of such licences provide valuable evidence for the dating of ancient buildings.

Machicolations

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.

History

Battlements have been used for thousands of years; the earliest known example is in the palace at Medinet-Abu at Thebes in Egypt, which allegedly derives from Syrian fortresses. Battlements were used in the walls surrounding Assyrian towns, as shown on bas reliefs from Nimrud and elsewhere. Traces of them remain at Mycenae in Greece, and some ancient Greek vases suggest the existence of battlements. The Great Wall of China has battlements.

Development

In the European battlements of the Middle Ages the crenel comprised one-third of the width of the merlon: the latter, in addition, could be provided with arrow-loops of various shapes (from simply round to cruciform), depending on the weapon being utilized. Late merlons permitted fire from the first firearms. From the 13th century, the merlons could be connected with wooden shutters that provided added protection when closed. The shutters were designed to be opened to allow shooters to fire against the attackers, and closed during reloading.

Ancient Rome

The Romans used low wooden pinnacles for their first aggeres (terreplains). 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.

Italy

Loop-holes were frequent in Italian battlements, where the merlon has much greater height and a distinctive cap. Italian military architects used the so-called Ghibelline or swallowtail battlement, with V-shaped notches in the tops of the merlon, giving a horn-like effect. This would allow the defender to be protected whilst shooting standing fully upright. The normal rectangular merlons were later nicknamed Guelph ^{[citation needed]}.

Arabia

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.

Decorative element

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.
