The courtyard of the mosque has been made 8–10 feet high from the plain ground.
The mosque has a total of 10 domes, 4 minarets (dome-shaped at the top), and 5 entrances.
The masonry of Bagha Mosque is made of lime and surki (powdered brick).
Besides, there is a shrine of Shahdaula and his five companions on the north side of the mosque premises.
Nasiruddin Nasrat Shah, son of the independent Sultan of Bengal Alauddin Hussain Shah, dug a dighi (large oblong pond) in front of the mosque for public welfare.
Every year during the winter, the area becomes famous for the chirping of innumerable guest birds.
Inside the mosque there is a special prayer room built a little higher in the north-west corner.
