A machicolation (french: mâchicoulis) is a floor opening between the supporting
corbels of a
battlement
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 inter ...
, through which stones or other material, such as boiling water, hot sand,
quicklime or boiling cooking oil, could be dropped on attackers at the base of a
defensive wall. A smaller version found on smaller structures is called a box-machicolation.
Terminology

The structures are thought to have originated as Crusader imitations of
mashrabiya.
The word derives from the
Old French
Old French (, , ; Modern French: ) was the language spoken in most of the northern half of France from approximately the 8th to the 14th centuries. Rather than a unified language, Old French was a linkage of Romance dialects, mutually intelligi ...

as ''machecollum'', probably from Old French ''machier'' 'crush', 'wound' and ''col'' 'neck'. ''Machicolate'' is only recorded in the 18th century in English, but a verb ''machicollāre'' is attested in
Anglo-Latin.
Both the Spanish and Portuguese words denoting this structure (''matacán'' and ''mata-cães'', respectively), are similarly composed from "matar canes" meaning roughly "killing dogs", the latter word being a
slur referring to
infidels.
[Villena (1988) p. ?.]
In Italy and countries which were influenced by the Italian language, such as Malta, it was known as ''piombatoio''.
Similar to a machicolation is a smaller version which opens similar to an enclosed balcony, generally from a tower rather than a larger structure. This is called a box-machicolation.
Description and use
The design of a machicoulis (sometimes called drop box) originates from the
Middle East
The Middle East ( ar, الشرق الأوسط, ISO 233: ) is a geopolitical region commonly encompassing Arabia (including the Arabian Peninsula and Bahrain), Asia Minor (Asian part of Turkey except Hatay Province), East Thrace (Europ ...
, where they are usually found on defensive walls. The original Arabian design is rather small, and similar to the domestic wooden balcony known as
mashrabiya.
In contrast to the domestic balcony, for purposes of defense, the Middle-East version of the machicoulis prominently features a wide opening at the bottom. The opening allows the dropping of hot water and other material intended to cause harm to the enemy below. The otherwise enclosed opening adapted from that of a closed balcony also provides cover from enemy attack while using it.
Machicolations were more common in French castles than English, where they were usually restricted to the gateway, as in the 13th-century
Conwy Castle. One of the first examples of machicolation that still exists in northern France is at the
Château de Farcheville
The Château de Farcheville is a 14th-century castle in the ''commune'' of Bouville near Paris in the ''département'' of Essonne.
The castle was built between 1290 and 1304, by Hughes II de Bouville and Hugues III, Lords of Farcheville and Bouv ...
built in 1291 outside Paris.
The origins are from
Syria
Syria ( ar, سُورِيَا or سُورِيَة, translit=Sūriyā), officially the Syrian Arab Republic ( ar, الجمهورية العربية السورية, al-Jumhūrīyah al-ʻArabīyah as-Sūrīyah), is a Western Asian country lo ...
and the Crusaders brought their design to Europe. Machicolations were a common feature in many towers in Rhodes, which were built by the
Knights Hospitallers.
After the Knights were given rule over
Malta, machicolations also became a common feature on rural buildings, until the 18th century. Buildings with machicolations include
Cavalier Tower,
Gauci Tower, the
Captain's Tower,
Birkirkara Tower
The Birkirkara Tower ( mt, Torri ta' Birkirkara), also known as Għar il-Ġobon Tower ( mt, Torri ta' Għar il-Ġobon), is a tower in Birkirkara, Malta. Its date of construction is not known, but it is believed to date back to around the mid or ...
, and
Tal-Wejter Tower.
A
hoarding is a similar structure made of wood, usually temporarily constructed in the event of a siege. Advantages of machicolations over wooden hoardings include the greater strength and fire resistance of stone.
Post-medieval use

Machicolation was later used for decorative effect with spaces between the
corbels but without the openings, and subsequently became a characteristic of many non-military buildings.
