Mashrabiya

A mashrabiya or mashrabiyya (Arabic: مشربية) is an architectural element which is characteristic of traditional architecture in the Islamic world and beyond. It is a type of projecting oriel window enclosed with carved wood latticework located on the upper floors of a building, sometimes enhanced with stained glass. It was traditionally used to catch wind and for passive cooling. Jars and basins of water could be placed in it to cause evaporative cooling. It is most commonly used on the street side of the building; however, it may also be used internally on the sahn (courtyard) side. The term mashrabiya is sometimes used of similar lattices elsewhere, for instance in a takhtabush. It is similar to Indian jali.

It has been used since the Middle Ages, reached a peak during the Ottoman period, but fell into decline in the late 19th century and the first half of the 20th century. However, interest in sustainable architecture has contributed to a revival of the mashrabiya and other elements of vernacular architecture.
