Also called Bari Masjid, Juma (Friday) Masjid or Jami Masjid, Jama Masjid is situated 2.2 km in the north-east of the city of Jaunpur. The 15th-century monument was built during the reign of Firoz Shah Tughlak in India. The design and style of its architecture bears close resemblance to Atala Masjid in the city as well as Mughal monuments in Delhi. The mosque is built on a six-metre-high platform, which can be reached by a flight of steps. It can be entered through a pylon-shaped gate which has two arches above it.
The main prayer hall of the mosque has tunnel vaults on its sides. Its huge dome has a diameter of 11.4 metres. It has small windows that enable the sunlight to enter the interior of the mosque. The interior and exterior of walls of the mosque are covered with typical Mughal style decorative art work.
