Wikipedia: Mashrabiya or Shanasheel (Arabic: مشربية or شناشيل‎) is the Arabic term given to a type of projecting oriel window enclosed with carved wood latticework located on the second storey of a building or higher, often lined with stained glass. The mashrabiya (sometimes shanshool or rushan) is an element of traditional Arabic architecture used since the Middle Ages up to the mid-20th century. It is mostly used on the street side of the building; however, it may also be used internally on the sahn (courtyard) side.
