This is Sidi Saiyyed Mosque, popularly known as Sidi Saiyyid ni Jali locally, built in 1572–73 AD (Hijri year 980), is one of the most famous mosques of Ahmedabad, a city in the state of Gujarat, India. The mosque was built by Sidi Sayyad, a Habshi nobleman, in 1572-73. The mosque is entirely arcuated and is known for its ten intricately carved stone latticework windows (jalis) on the side and rear arches. The rear wall is filled with square stone pierced panels in geometrical designs. The two bays flanking the central aisle have reticulated stone slabs carved in designs of intertwined trees and foliage and a palm motif. This intricately carved lattice stone window is the Sidi Saiyyed Jali, the unofficial symbol of city of Ahmedabad and the inspiration for the design of the logo of the Indian Institute of Management Ahmedabad.
