To the south of the Bara Gumbad is Bahram Khan's three-domed structure, commissioned in 1744, which serves as the primary mosque of the compound. Each of its domes has tall finials and rest on crenelated drums. Like the Bara Gumbad, its eastern side has three arched doors, the middle also larger, as well as a modern veranda. The mosque was damaged during the 1897 Assam earthquake, requiring repairs by the Magistrate of Sylhet, John Willes. A smaller mosque stands on the western side of Shah Jalal's grave and forms a part of the enclosure. Three-domed and likely originally also constructed by Farhad Khan, it was rebuilt in the same design and style in the late-18th century by the then Collector of Sylhet. A fourth mosque, erected by Abdullah Shirazi, lies on the eastern bank of the tank reservoir.
