The three domed mosque above the platform, now transformed into a multi-storied structure was originally a copy of Shaista Khan's another three domed mosque at the Mitford Hospital compound near the Buriganga River.

The promenade around the three domed prayer chamber, since there was no separate structure for study purpose, might have been used for open-air classes and the vaulted room with book-shelves on their walls underneath the platform may have been designed to provide residential accommodation for those who used to teach and study here.

It is an ingenious[peacock prose] way of accommodating two structures-a madrasa and a mosque in a single building which not only saved space but also a considerable amount of money.

The construction has been dated to 1664, as noted by an inscription in the Persian language over a doorway.

So far known this is the earliest dated mosque in the History of Muslim Architecture in Bengal built on a high vaulted platform.
