Stucco decoration in Islamic architecture

Stucco decoration in Islamic architecture refers to carved or molded stucco and plaster. The terms "stucco" and "plaster" are used almost interchangeably in this context to denote most types of stucco or plaster decoration with slightly varying compositions. This decoration was mainly used to cover walls and surfaces and the main motifs were those predominant in Islamic art: geometric, arabesque (or vegetal), and calligraphic, as well as three-dimensional muqarnas. Plaster of gypsum composition was extremely important in Islamic architectural decoration as the relatively dry climate throughout much of the Islamic world made it easy to use this cheap and versatile material in a variety of spaces.

Stucco decoration was already used in ancient times in the region of Iran and the Greco-Roman Mediterranean. In Islamic architecture, stucco decoration appeared during the Umayyad period (late 7th–8th centuries) and underwent further innovations and generalization during the 9th century under the Abbasids in Iraq, at which point it spread further across the Islamic world and was incorporated into regional architectural styles. Examples of historic carved stucco decoration are found in Egypt, Iran, Afghanistan, and India, among other areas. It was commonly used in "Moorish" or western Islamic architecture in the Iberian Peninsula (Al-Andalus) and parts of North Africa (the Maghreb), since at least the Taifa and Almoravid periods (11th–12th centuries). In the Iberian Peninsula it reached a creative pinnacle in Moorish architecture during the Nasrid dynasty (1238–1492), who built the Alhambra. Mudejar architecture also made broad use of such decoration.
