Bab Al-Futuh
Bab al-Futuh ( ar, باب الفتوح, , Conquest Gate) is one of three remaining gates in the city wall of the old city of Cairo, Egypt. It is located at the northern end of al-Mu'izz Street. The other two remaining gates are Bab al-Nasr (Victory Gate) in the north and Bab Zuwayla (Gate of Zuwayla) in the south. The gate was built during the Fatimid period, originally in the 10th century, then rebuilt in its current form in the late 11th century. History When Cairo was originally founded in 969 by the Fatimid general Jawhar, on behalf of Caliph al-Mu'izz, it was surrounded by a set of city walls built in brick and pierced by multiple gates. Later, during the reign of Caliph al-Mustansir, the vizier and army commander Badr al-Gamali rebuilt the city walls and its gates in stone. The present gate was thus completed in 1087, along with the neighbouring Bab al-Nasr gate. Bab al-Futuh was originally called ''Bab al-Iqbal'', or “the Gate of Prosperity”, but was given its presen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Machicoulis
A machicolation (french: mâchicoulis) is a floor opening between the supporting corbels of a battlement, 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 word ''machecol'', mentioned in Medieval Latin 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.V ...

Byzantine Architecture
Byzantine architecture is the architecture of the Byzantine Empire, or Eastern Roman Empire. The Byzantine era is usually dated from 330 AD, when Constantine the Great moved the Roman capital to Byzantium, which became Constantinople, until the fall of the Byzantine Empire in 1453. However, there was initially no hard line between the Byzantine and Roman empires, and early Byzantine architecture is stylistically and structurally indistinguishable from earlier Roman architecture. This terminology was introduced by modern historians to designate the medieval Roman Empire as it evolved as a distinct artistic and cultural entity centered on the new capital of Constantinople (modern-day Istanbul) rather than the city of Rome and its environs. Its architecture dramatically influenced the later medieval architecture throughout Europe and the Near East, and became the primary progenitor of the Renaissance and Ottoman architectural traditions that followed its collapse.

Pendentive
In architecture, a pendentive is a constructional device permitting the placing of a circular dome over a square room or of an elliptical dome over a rectangular room. The pendentives, which are triangular segments of a sphere, taper to points at the bottom and spread at the top to establish the continuous circular or elliptical base needed for a dome. In masonry the pendentives thus receive the weight of the dome, concentrating it at the four corners where it can be received by the piers beneath. Prior to the pendentive's development, builders used the device of corbelling or squinches in the corners of a room. Pendentives commonly occurred in Orthodox, Renaissance, and Baroque churches, with a drum with windows often inserted between the pendentives and the dome. The first experimentation with pendentives began with Roman dome construction in the 2nd–3rd century AD, while full development of the form came in the 6th-century Eastern Roman Hagia Sophia at Constantinople. ...

Al-Hakim Mosque
The Mosque of al-Hakim ( ar, مسجد الحاكم بأمر الله, Masjid al-Ḥākim bi Amr Allāh), nicknamed al-Anwar ( ar, الانور, lit=the Illuminated), is a historic mosque in Cairo, Egypt. It is named after Al-Hakim bi-Amr Allah (985–1021), the sixth Fatimid caliph and 16th Ismaili Imam. Construction of the mosque was originally started by Caliph al-'Aziz, the son of al-Mu'izz and the father of al Hakim, in 990 AD. It was completed in 1013 by al-Hakim, which is why it is named after him. The mosque is located in Islamic Cairo, on the east side of al-Mu'izz Street, just south of Bab al-Futuh (the northern city gate). In the centuries since its construction the mosque was often neglected and re-purposed for other functions, eventually falling into ruin. A major restoration and reconstruction of the mosque by the Dawoodi Bohras was completed in 1980, reopening it for religious use. History Fatimid construction and modifications The mosque's construction was i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Minaret
A minaret (; ar, منارة, translit=manāra, or ar, مِئْذَنة, translit=miʾḏana, links=no; tr, minare; fa, گلدسته, translit=goldaste) is a type of tower typically built into or adjacent to mosques. Minarets are generally used to project the Muslim call to prayer ('' adhan''), but they also served as landmarks and symbols of Islam's presence. They can have a variety of forms, from thick, squat towers to soaring, pencil-thin spires. Etymology Two Arabic words are used to denote the minaret tower: ''manāra'' and ''manār''. The English word "minaret" originates from the former, via the Turkish version (). The Arabic word ''manāra'' (plural: ''manārāt'') originally meant a "lamp stand", a cognate of Hebrew '' menorah''. It is assumed to be a derivation of an older reconstructed form, ''manwara''. The other word, ''manār'' (plural: ''manā'ir'' or ''manāyir''), means "a place of light". Both words derive from the Arabic root ''n-w-r'', which has a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salient (military)
A salient, also known as a bulge, is a battlefield feature that projects into enemy territory. The salient is surrounded by the enemy on multiple sides, making the troops occupying the salient vulnerable. The opponent's front line that borders a salient is referred to as a re-entrant – that is, an angle pointing inwards. A deep salient is vulnerable to being "pinched off" through the base, and this will result in a pocket in which the forces in the salient become isolated and without a supply line. On the other hand, a breakout of the forces within the salient through its tip can threaten the rear areas of the opposing forces outside it, leaving them open to an attack from behind. Implementation Salients can be formed in a number of ways. An attacker can produce a salient in the defender's line by either intentionally making a pincer movement around the military flanks of a strongpoint, which becomes the tip of the salient, or by making a broad, frontal attack which is held u ...

Kufic
Kufic script () is a style of Arabic script that gained prominence early on as a preferred script for Quran transcription and architectural decoration, and it has since become a reference and an archetype for a number of other Arabic scripts. It developed from the Arabic alphabet in the city of Kufa, from which its name is derived. Kufic script is characterized by angular, rectilinear letterforms and its horizontal orientation. There are many different versions of Kufic script, such as square Kufic, floriated Kufic, knotted Kufic, and others. History Origin of the Kufic script Calligraphers in the early Islamic period used a variety of methods to transcribe Qur’an manuscripts. Arabic calligraphy became one of the most important branches of Islamic Art. Calligraphers came out with the new style of writing called Kufic. Kufic is the oldest calligraphic form of the various Arabic scripts. The name of the script derives from Kufa, a city in southern Iraq which was considere ...

Molding (decorative)
Moulding (spelled molding in the United States), or coving (in United Kingdom, Australia), is a strip of material with various profiles used to cover transitions between surfaces or for decoration. It is traditionally made from solid milled wood or plaster, but may be of plastic or reformed wood. In classical architecture and sculpture, the moulding is often carved in marble or other stones. A "plain" moulding has right-angled upper and lower edges. A "sprung" moulding has upper and lower edges that bevel towards its rear, allowing mounting between two non-parallel planes (such as a wall and a ceiling), with an open space behind. Mouldings may be decorated with paterae as long, uninterrupted elements may be boring for eyes. Types Decorative mouldings have been made of wood, stone and cement. Recently mouldings have been made of extruded PVC and Expanded Polystyrene (EPS) as a core with a cement-based protective coating. Synthetic mouldings are a cost-effective alternative ...

Arrowslit
An arrowslit (often also referred to as an arrow loop, loophole or loop hole, and sometimes a balistraria) is a narrow vertical aperture in a fortification through which an archer can launch arrows or a crossbowman can launch bolts. The interior walls behind an arrow loop are often cut away at an oblique angle so that the archer has a wide field of view and field of fire. Arrow slits come in a variety of forms. A common one is the cross, accommodating the use of both the longbow and the crossbow. The narrow vertical aperture permits the archer large degrees of freedom to vary the elevation and direction of their bowshot, but makes it difficult for attackers to harm the archer since there is only a small target at which to aim. Balistraria, plural balistrariae, from balister, crossbowman can often be found in the curtain walls of medieval battlements beneath the crenellations. History The invention of the arrowslit is attributed to Archimedes during the siege of Syracuse in 2 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Voussoir
A voussoir () is a wedge-shaped element, typically a stone, which is used in building an arch or vault. Although each unit in an arch or vault is a voussoir, two units are of distinct functional importance: the keystone and the springer. The keystone is the centre stone or masonry unit at the apex of an arch. The springer is the lowest voussoir on each side, located where the curve of the arch springs from the vertical support or abutment of the wall or pier. The keystone is often decorated or enlarged. An enlarged and sometimes slightly dropped keystone is often found in Mannerist arches of the 16th century, beginning with the works of Giulio Romano, who also began the fashion for using voussoirs above rectangular openings, rather than a lintel (Palazzo Stati Maccarani, Rome, circa 1522). The word is a stonemason's term borrowed in Middle English from French verbs connoting a "turn" (''OED''). Each wedge-shaped voussoir ''turns aside'' the thrust of the mass above, transf ...

Blind Arch
A blind arch is an arch found in the wall of a building that has been infilled with solid construction and so cannot serve as a passageway, door or window.''A Dictionary of Architecture''; Fleming, John; Honour, Hugh & Pevsner, Nikolaus (1966) The term is most often associated with masonry wall construction, but blind arches are also found (or simulated) in other types of construction such as light frame construction. Some blind arches were originally built as open arches and infilled later. Others were originally built with solid infill as intentional stylistic elements. See also * Blind arcade * Lombard band * Lesene A lesene, also called a pilaster strip, is an architectural term for a narrow, low-relief vertical pillar on a wall. It resembles a pilaster, but does not have a base or capital. It is typical in Lombardic and Rijnlandish architectural building ...
