The village of Qasba was an important center in the
Sultanate of Bengal and was home to several influential Muslim families. The mosque was constructed in the early 16th century, during the reign of
Alauddin Husain Shah. The earlier
Nine Dome Mosque built by
Khan Jahan Ali in
Khalifatabad is considered to be Qasba Mosque's inspiration due to the striking similarities. Despite the mosque's Sultanate origins, locals often credit the mosque to
Sabi Khan, the Mughal
faujdar of
Bakla who built several mosques and roads in the region. In active use, the mosque is a protected monument by
Bangladeshi Department of Archaeology. ==Architecture==
