There is an austere simplicity about this enormous structure. It stands on a 4.6 m high plinth accessed by an impressive flight of steps. The whole mosque covers an area of 97.4 sq m and its porch, atop the flight of steps, is dominated by a 16.8 m dome. As demanded by congregational religions, beyond the porch is the great open court surrounded by arched colonnades. On the far side of the court is the Prayer Hall with its pulpit atop a flight of steps, and arches extending away to the right and left. Do devote a little time to the construction of the ceiling crowned by three large domes and fifty eight smaller ones.
The seventeen mihrabs here, to cater to large numbers of the faithful, are the most decorated features in this huge mosque. White stone, chiselled with the delicacy of metal filigree, stands out against their polished black backgrounds. While there is no official explanation for the presence of the fifty-eight small domes along with the three large ones, it seems fairly obvious why they were installed. Long before Thomas Alva Edison invented the microphone in 1877, Mandu's architects had designed the domes as sound amplifying devices to carry the words of the, often feeble and old, preacher to the entire congregation. The Jami Masjid, said to have been patterned on the great mosque in Damascus, was started by Hoshang Shah and completed by Mahmud Khalji in 1454.
