Masjid-i-Jehan-Numa, also known as Jama Masjid, is one of the largest mosques in India, commissioned by Mughal Emperor Shah Jahan and completed between 1644 and 1656. Constructed primarily of red sandstone with white marble accents, it features imposing domes, two tall minarets, and a vast courtyard capable of accommodating thousands of worshippers, exemplifying grand Mughal architectural style.
