The courtyard of the Masjid can hold up to twenty-five thousand worshippers. The Masjid also houses several relics in a closet in the north gate, including a copy of the Qur'an written

The Jama Masjid's floorplan is very similar to the Moti Masjid at Agra, but the Jama Masjid is the bigger and more imposing of the two. Its majesty is further enhancedbecause of the high ground that he selected for building this Masjid.
