Located near Lal Darwaza in Ahmedabad, the Sidi Sayyad Mosque is world renowned for its intricate stone carvings, especially for its ten unique and splendid semi-circular tracery windows. The tracery resembles the famous silver filigree work, depicting the intricate intertwining of the branches of a tree. Constructed in 1572-73 by Sidi Sayyad, a salve of Ahmed Shah, the mosque presents a fine example of Indo-Saracenic architecture. The interior of the Sidi Sayyad Mosque is uniquely divided into 15 areas with differing inner dome-style. The mosque has a total of ten intricately carved stone windows. Two of them (western windows) have unmatched exquisite naturalistic patterns and the remaining eight have jail workmanship of square grid pattern. Their popularity can be assessed from the fact that the wooden models of the western windows have been kept in the museums of New York and Kensington. You can also buy the mosque's models in miniature, which can be perfect souvenirs for your friends and family.
