Located to the west of Shait Gumbad Mosque across the Ghora dighi is the Bibi Begni’s Mosque, measuring 14.6m square. This single domed mosque shows resemblance with Singar Mosque in general appearance except that it is larger and massively built. The building has three entrances on the east and one each on south and north sides. The central doorway is larger. The corner turrets are relieved with bands of mouldings at regular intervals.

The western wall is projected westward in its middle which is flanded by two engaged small unusual round towers ornated with horizontal bands and terracottas.

The multi-cusped mihrabs are embellished with terracotta floral motifs and bordered with terracotta floral motifs and bordered with rectangular mouldings. In the center of each mihrab chain-and-bell motif is prominent. The spandrels of each mihrab are decorated with rosettes on either side. Intertwined geometric motifs and blind merlons run in parallel rows over the spandrels. The building has eight engaged round pilasters-two in each wall. The curved cornice runs through the corner turrets.
