No, the Jama Masjid is not the largest mosque in India. The honor of being the largest mosque in India goes to the Taj-ul-Masajid, located in Bhopal, Madhya Pradesh. The Jama Masjid, however, is one of the largest and most well-known mosques in India. Built in 1656 by Mughal Emperor Shah Jahan, it is one of the last architectural legacies of his reign. The mosque has a massive courtyard that can accommodate up to 25,000 worshippers at a time. Its main prayer hall has three domes and is adorned with intricate calligraphy and carvings.
