Illustration of a pillar from the Jama Masjid from James Burgess' 'Original Drawings [of] Muhammadan Architecture of Ahmadabad.' The Jami Masjid at Ahmadabad, Gujarat, was built by Sultan Ahmad Shah (r.1411-42) who founded the city of Ahmadabad in 1411 and was responsible for the construction of several buildings and mosques. The Jami Masjid, built c.1424, was constructed as the principal Friday mosque in the centre of the city. The imposing structure is entered from the north side and leads into the courtyard and prayer hall supported by 260 columns. These columns divide the prayer hall into fifteen bays which are crowned by fifteen domes. The central nave of the prayer hall is split into three levels. Along the balconies of the upper levels, there are enclosed spaces for private prayers, separated with beautifully decorated perforated screens. These areas were used by women or the Sultan. In the centre of the courtyard there is a water tank.
