These are pictures of Jalis found on various Islamic architectures found in India. A Jali is the term for a perforated stone or latticed screen, usually with ornamental pattern constructed through the use of calligraphy and geometry. Earlier Jalis were prepared by carving into the stone but Mughals engaged the technique of inlay, using marble and semiprecious stone. Jalis with its intricate design also have its physical importance in the monuments; they provide privacy and also keep ventilation to keep the inside cool. Jalis act as thin contact between the outside and inside spaces of the monument where in the people can sit converse while enjoying the outside glimpses as well.
