This mosque is the perfect example for the architectural ornamentation of Saltanat period

From outside the mosque with its four heavy and attractive corner towers and seventy-seven domes over the roof, offers a wonderful spectacle to the eye, while its interior is imposing. architecturally the mosque shows the continuity of the building style that had already been started in bengal and also some new developments taking inspiration both from the region and from outside. its bastion-like tapering corner towers with their rounded cupolas and two-storied conception, which rises high above the roof, appears to have been dictated by similar tughlaqian examples of the khirki (c 1375) and the kalan mosques (1380) at delhi. the circular shape of these corner towers is worth noting as it distinguishes the khan jahani group of monuments from other buildings of khalifatabad. The interior plan of the mosque - a large central nave with the side wings - follows a style noticed for the first time in bengal in the adina mosque (1375), which in turn might have been derived from other earlier mosques erected in imitation of the damascus jami (705-15). the chau-chala vaults over the central nave, hitherto not used in bengal architecture and noticed subsequently in the chhota sona mosque (1493-1519) and the lattan mosque (early 16th century) at gaur, appear to have originated from the chau-chala huts of bengal. The beautiful triangular pediment over the central doorway in the eastern facade may also be said to have been copied from the gable ends of the do-chala hut of the land. Similarly a series of off-set and recessed chases in the outer surface of the walls are likely to have been in imitation of the frame-work of the wood and wattle hut of Bengal. An important feature of the mosque, though unusual in Bengal but noticed in many congregational mosques in northern India, is a small doorway in the back wall beside the central mihrab, the idea of which might have originally been borrowed from those of early mosques in Islam. In early Islam the postern opening of the mosque is known to have been used exclusively by the caliphs, governors or imams. It is therefore not unlikely that the western doorway of the Shait gambuj Mosque was reserved for Khan Jahan, the governor of Khalifatabad, who had his residence a few yards away to the north of the mosque. Of the two brick platforms, already cited, the one near the central mihrab was perhaps used by Khan Jahan while transacting administrative business, and the other near an eastern doorway was perhaps meant for a religious teacher, who sat on it and expounded Islamic teachings to the people or students. The Shait gambujMosque therefore appears to have served triple purposes - a congregational mosque, a parliament or assembly hall like those of early Islam and a madrasa like the Isfahan Jami and the Masjid-i-Jami at Ardistan in Persia.
