A merlon is the solid upright section of a battlement (a crenellated parapet) in medieval architecture or fortifications. [1] Merlons are sometimes pierced by narrow, vertical embrasures or slits designed for observation and fire. The space between two merlons is called a crenel, and a succession of merlons and crenels is a crenellation. [2] Crenels designed in later eras for use by cannons were also called embrasures. [3]
The term merlon comes from the French language, adapted from the Italian merlone, possibly a shortened form of mergola, connected to Latin mergae (pitchfork), or from a diminutive moerulus, from murus or moerus (a wall). An alternative etymology suggests that the medieval Latin merulus (mentioned from the end of the 10th century) functioned as a diminutive of Latin merle, "blackbird", expressing an image of this bird sitting on a wall.
As an essential part of battlements, merlons were used in fortifications for millennia. The best-known examples appear on medieval buildings, where battlements, though defensive, could be attractively formed, thus having a secondary decorative purpose. Some (especially later) buildings have false "decorative battlements". The two most notable European variants in Middle Ages merlons shape were the Ghibelline and the Guelph merlon: the former ended in the upper part with a swallow-tailed form, while the latter term indicates the normal rectangular shape merlons (wimperg).
Other shapes include: three-pointed, quatrefoil, shielded, flower-like, rounded (typical of Islamic and African world), pyramidal, etc., depending either from the type of attacks expected or aesthetic considerations.
In Roman times, the merlons had a width sufficient to shelter a single man. As new weapons appeared in the Middle Ages (including crossbows and the first firearms), the merlons were enlarged and provided with loop-holes of various dimensions and shapes, varying from simply rounded to cruciform. From the 13th century, the merlons could also be used to pivot wooden shutters; these added further protection for the defenders when they were not firing, or were firing downwards near the base of the wall. The shutters, also known as mantlets, could be opened by hand, or by using a pulley.
After falling out of favour when the invention of the cannon forced fortifications to take a much lower profile, merlons re-emerged as decorative features in buildings constructed in the neo-Gothic style of the 19th century.
Medieval fortification refers to medieval military methods that cover the development of fortification construction and use in Europe, roughly from the fall of the Western Roman Empire to the Renaissance. During this millennium, fortifications changed warfare, and in turn were modified to suit new tactics, weapons and siege techniques.
A castle is a type of fortified structure built during the Middle Ages predominantly by the nobility or royalty and by military orders. Scholars usually consider a castle to be the private fortified residence of a lord or noble. This is distinct from a mansion, palace and villa, whose main purpose was exclusively for pleasance and are not primarily fortresses but may be fortified. Use of the term has varied over time and, sometimes, has also been applied to structures such as hill forts and 19th- and 20th-century homes built to resemble castles. Over the Middle Ages, when genuine castles were built, they took on a great many forms with many different features, although some, such as curtain walls, arrowslits, and portcullises, were commonplace.
Medieval architecture was the art of designing and constructing buildings in the Middle Ages. Major styles of the period include pre-Romanesque, Romanesque, and Gothic. The Renaissance marked the end of the medieval period, when architects began to favour classical forms. While most surviving medieval constructions are churches and military fortifications, examples of civic and domestic architecture can be found throughout Europe, including in manor houses, town halls, almshouses, bridges, and residential houses.
A parapet is a barrier that is an upward extension of a wall at the edge of a roof, terrace, balcony, walkway or other structure. The word comes ultimately from the Italian parapetto. Where extending above a roof, a parapet may simply be the portion of an exterior wall that continues above the edge line of the roof surface, or may be a continuation of a vertical feature beneath the roof such as a fire wall or party wall. Parapets were originally used to defend buildings from military attack, but today they are primarily used as guard rails, to conceal rooftop equipment, reduce wind loads on the roof, and to prevent the spread of fires.
A motte-and-bailey castle is a European fortification with a wooden or stone keep situated on a raised area of ground called a motte, accompanied by a walled courtyard, or bailey, surrounded by a protective ditch and palisade. Relatively easy to build with unskilled labour, but still militarily formidable, these castles were built across northern Europe from the 10th century onwards, spreading from Normandy and Anjou in France, into the Holy Roman Empire, as well as the Low Countries it controlled, in the 11th century, when these castles were popularized in the area that became the Netherlands. The Normans introduced the design into England and Wales. Motte-and-bailey castles were adopted in Scotland, Ireland, and Denmark in the 12th and 13th centuries. By the end of the 13th century, the design was largely superseded by alternative forms of fortification, but the earthworks remain a prominent feature in many countries.
An embrasure is the opening in a battlement between two raised solid portions (merlons). Alternatively, an embrasure can be a space hollowed out throughout the thickness of a wall by the establishment of a bay. This term designates the internal part of this space, relative to the closing device, door or window. In fortification this refers to the outward splay of a window or of an arrowslit on the inside.
A battlement, in defensive architecture, such as that of city walls or castles, comprises a parapet, 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 embrasures, also known as crenels or crenelles, and a wall or building with them is described as crenellated; alternative older terms are castellated and embattled. The act of adding crenels to a previously unbroken parapet is termed crenellation.
Enceinte is a French term that refers to the "main defensive enclosure of a fortification". For a castle, this is the main defensive line of wall towers and curtain walls enclosing the position. For a settlement, it would refer to the main town wall with its associated gatehouses, towers, and walls.
The existence of the earliest forts in India have been substantiated by documentation and excavation. In the medieval times, the architecture of the forts had both Hindu and Muslim influence. The forts constructed by the British initially opted for simple designs. The existing castles are continually modified and many of them are privately owned.
The Château de Kaysersberg is a ruined castle in the commune of Kaysersberg in the Haut-Rhin département of France.
An arrowslit is a narrow vertical aperture in a fortification through which an archer can launch arrows or a crossbowman can launch bolts.
A curtain wall is a defensive wall between two fortified towers or bastions of a castle, fortress, or town.
A chemin de ronde, also called an allure, alure or, more prosaically, a wall-walk, is a raised protected walkway behind a castle battlement.
Visconti Castle Italian: Castello Visconteo is a castle in Locarno, Switzerland. It is a Swiss heritage site of national significance.
In medieval fortification, a bretèche or brattice is a small balcony with machicolations, usually built over a gate and sometimes in the corners of the fortress' wall, with the purpose of enabling defenders to shoot or throw objects at the attackers huddled under the wall. Depending on whether they have a roof, bretèches are classified in two types: open and closed. The open ones were accessed from the battlement's wall walk, or from a crenel.
The Castle of Beja is a medieval castle in the civil parish of Beja, municipality of Beja, Portuguese district of Beja.
The Rocca di Urbisaglia is a 16th-century military fortification, including ruins of medieval fortifications and Roman walls.
Its imposing position, dominating the urban area and the Fiastra Valley below, suggests that the Arx or the Capitol of the Roman town Urbs Salvia was once located here.
