Qasba

Qasba in southern Bengal is known for a nine-domed mosque built in the style associated with Khan Jahan of Khalifatabad. Its square prayer hall is divided into bays beneath the domes, and corner towers frame the building. The design closely resembles the nine-domed mosque at Bagerhat and the Masjidkur mosque farther west, showing how a shared architectural tradition spread among the settlements of the delta.
