Bibiji Masjid is a historical mosque located in the Rajapur section of Ahmedabad, once a suburb to the southeast of the old walled city. An inscription dates the building to 1454 CE. The mosque is a rectangular in form, opening onto a large open space on its east side. The east facade is divided into five portions. The central portion is occupied by a monumental archway flanked by two minarets. Flanking this on either side is a smaller arched portal, and finally on either end of the facade is a triple-arched portal.
The interior of the prayer hall reflects the five-fold division of the exterior. The interior is one large pillared hall, marked by five large domed bays across the center of the space that align with the five entrance portals. Two aisles separate the domed bays from the portals, as well as from the qibla wall. One aisle separates the domed bays from one another and from the side walls. Every other bay on the qibla aisle and the aisle just behind the entrance portals is vaulted. The central section of the interior (behind the central portal), is elevated higher than the four side sections, and a second story gallery open to the exterior and accessed by stairwells in the minarets provides light for the prayer hall. A mihrab marks the qibla behind each of the five large domed bays, and beteween each mihrab and the end mihrabs and the side walls is a window. Three windows pierce the side walls and four open from the front wall.
