Most historians suggest that Shaista Khan, the Mughal governor of the Bengal Subah from 1664 to 1688, built the mosque within a fortified complex in the early 1680s.

Presumed to be Bibi Maryam's father, Khan named the site after his daughter's premature demise and also had her tomb built nearby.

[1] Historians who have examined the building materials and applied construction techniques have found that both were exercised contemporaneously with Nawab Shaista Khan.

According to the present mosque authority, Shaista Khan's family and administration formed the Muslim population of present-day Killarpul during its construction, which explains the limited accommodation.

These mihrabs have been compressed in width and shortened in height; otherwise, they would structurally relate to the three domes to portray one of the site's prime architectural essences.

A combination of embellishments and proportional adjustment among elements such as arches, domes, mihrabs etc., defines the architecture of the Bibi Maryam Mosque.

The embellishment of the outer surfaces or walls, which in the contemporary typical Mughal mosques were plaques and floral and geometric motifs, are also untraceable.

Unlike the Bibi Maryam Masjid, the shrine has retained all its architectural qualities despite undergoing conservation numerous times.

Another building adjoined the fortified walls in the south direction, which was the dwelling of Nawab's soldiers who guarded the complex.

The shrine has been built on an elevated platform which measures three feet high and is accessed by an open staircase whose appearance is ruined.

Although the plaques and motifs which adorned the Bibi Maryam Masjid disappeared long ago, their themes can still be deduced by analysing those still preserved in the shrine and other buildings of the complex.

The scarcity of the information is attributed to its faint documentation in the context of history and the government's irresponsibility in treating it as a national heritage.

However, it is not dilapidated since a lot can be traced from the surviving elements, such as domes, arches and load-bearing walls that defined the space in its inception.
