At the eastern side of Teen Darwaza, Jama Masjid is located opposite to Mahatma Gandhi Road. It is one of the most beautiful mosques in India. The grand edifice was built by Ahmed Shah in 1423 A.D. from the items ransomed from the demolished Hindu and Jain temples.

Built in yellow sand stones, this marvelous mosque has a combination of Hindu and Muslim styles of architecture. There are about 260 columns within the mosque to protect its roof. There used be two shaking minarets as well but they got completely demolished during the earthquake of 1819 and 1957.

It is believed that the large black slab around the main arc is actually the base of a Jain idol, buried upside down by the Sultan.
