Saat Masjid, Archaeological mosque in Mohammadpur Thana, Bangladesh

Saat Masjid is a rectangular Mughal mosque with three large bulbous domes over the prayer hall and four smaller domes at the corners, giving it seven in all. Its red stone facade has three cusped entrance arches on the east, and the north and south ends are marked by double-storied corner pavilions. Inside, three mihrabs pierce the west wall, and the central one carries two rows of cusping in moulded plaster.

The mosque dates from the reign of Mughal emperor Aurangzeb. Its construction is traditionally attributed to Shaista Khan, governor of Bengal from 1678 to 1684, though no inscription on the building confirms this. Bengali sources credit his son Umid Khan with building it around 1680. It is one of several Mughal mosques raised in Dhaka in that period.

The name means "Seven Domed Mosque": three large domes crown the roof and four smaller ones sit at the corners. Beside the east side stands Bibir Mazar, said to be the tomb of Shaista Khan's daughter, octagonal inside and square outside, now restored. A garden lies in front of the mosque.

The mosque sits near Mohammadpur Bus Stand and can be reached by following the road through Bashbari toward the Shia Mosque complex. Visitors should dress appropriately and remember this is an active place of worship.

The complex houses an octagonal tomb called Bibir Mazar, believed to be the burial site of Shaista Khan's daughter. This mausoleum displays a different architectural style from the main prayer building and is often overlooked by visitors.
