Islamic architectural feature For the academic journal, see Muqarnas (journal) . Muqarnas as seen from below in the iwan entrance to the Shah Mosque in Isfahan , Iran (17th century) Muqarnas dome in the Sala de Dos Hermanas at the Alhambra in Granada , Spain (14th century) Muqarnas ( Arabic : مقرنص ), also known in Iberian architecture as Mocárabe (from Arabic: مقربص , romanized: muqarbaṣ ), is a form of three-dimensional decoration in Islamic architecture in which rows or tiers of niche-like elements are projected over others below. It is an archetypal form of Islamic architecture, integral to the vernacular of Islamic buildings, and typically featured in domes and vaults, as well as iwans , entrance portals, or other niches. It is sometimes referred to as "honeycomb vaulting" or "stalactite vaulting". The muqarnas structure originated from the squinch . Its purpose is to create a smooth, decorative zone of transition in an otherwise bare, structural space. This structure gives the ability to distinguish between the main parts of a building and serves as a transition from the walls of a square or rectangular room to a round dome or vault above it. Muqarnas could also form entire vaults and domes. From below, these compositions can create an elaborate visual effect based on the interplay of light and shadow across the surfaces sculpted into three-dimensional patterns. Muqarnas most likely first developed in eleventh-century Iraq , though the earliest preserved examples are also found outside this region. As the technique became widespread in the 12th century, regional styles and variations developed across the Islamic world. The Grove Encyclopedia of Islamic Art and Architecture .

Muqarnas in the Alhambra Palace, Granada , Spain Muqarnas (Arabic: مقرنص) is a type of corbel used as a decorative device in traditional Islamic and Persian architecture . The term is similar to mocárabe , but mocárabe only refers to designs with formations resembling stalactites , by the use of elements known as alveole . Muqarnas takes the form of small pointed niches, stacked in tiers projecting beyond those below and can be constructed in brick, stone, stucco or wood. They are often applied to domes , pendentives , cornices, squinches and the undersides of arches and vaults . Muqarnas is the Arabic word for stalactite vault, an architectural ornament developed around the middle of the tenth century in north eastern Iran and almost simultaneously, but apparently independently, in central North Africa. It involves three-dimensional architectural decorations composed of niche-like elements arranged in tiers. The two-dimensional projection of muqarnas vaults consists of a small variety of simple geometrical elements. The earliest example of muqarnas can be found near Samarra , Iraq, at Sharaf al-Dawla Mausoleum, also known as Imam Dur Mausoleum, the Uqaylid ruler. Examples can be found in the Alhambra in Granada , Spain, the Abbasid Palace in Baghdad , and the mausoleum of Sultan Qaitbay , Cairo , Egypt .

Muqarnas in the iwan entrance to the Shah Mosque in Isfahan , Iran Muqarnas on the underside of an arch, Alhambra Palace , Granada , Spain , likely in carved plaster.Muqarnas corbel , Qutb Minar , India The muqarnas ( ; ) is a form of architectural ornamented vaulting , the "geometric subdivision of a squinch , or cupola , or corbel , into a large number of miniature squinches, producing a sort of cellular structure", sometimes also called "honeycomb" vaults from their resemblance to these.They are used for domes, and especially half-domes in entrances and apses , mostly in traditional Islamic and Persian architecture.When some elements project downwards, the style may be called mocárabe ; these are reminiscent of stalactites , and are may be called "stalactite vaults".Muqarnas developed around the middle of the 10th century in northeastern Iran and almost simultaneously — but seemingly independently — in central North Africa. Examples can be found in the Alhambra in Granada , Spain , the Abbasid Palace in Baghdad , Iraq , and the mausoleum of Sultan Qaitbay , Cairo , Egypt . Large rectangular roofs in wood with muqarnas-style decoration adorn the 12th century Cappella Palatina in Palermo , Sicily , and other important buildings in Norman Sicily .They are also found in Armenian architecture .A Dictionary of Architecture and Landscape Architecture (Paperback) (2nd ed.).
