The Sidi Saiyad Mosque was built in the last year of the existence of Sultanate of Gujarat. The mosque is entirely arcuated and is famous for beautifully carved ten 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 stone window is the Siddi Sayyed Jali, the unofficial symbol of city of Ahmedabad and the inspiration for the design of the logo of the Indian Institute of Management Ahmedabad. This mosque is extremely strong as since it is made of stones and in stones after many years it goes back to the ground and they by day it becomes much more stronger.
