Lying southwest of the Bhadra Fort, this mosque is among Sultan Ahmed Shah's finest pieces of architecture. It was built in the year 1414 and is one of the oldest structures in the city. It comprises prayer halls, called mehrabs, which are made in black and white marble with detailed carvings. All the prayer halls have stone pillars, jaalis (lattice) work on ceilings and ornate carvings. Moreover, there are dome-like cupolas in every hall. There is a separate chamber with a prayer room for women in the northeast corner of the mosque, popularly known as zenana. When built, the mosque was meant to be a place of worship exclusively for the royals. Currently, it is one of the most-sought tourist attractions in Ahmedabad.
