The Jama Masjid is one of the oldest and largest mosques in India flaunting the Mughal architectural finesse. It was built by Shah Jahan in 1658 to be employed as the emperor's primal worship site. Situated in old Delhi the Jama Masjid imposes the Mughal architectural artifice and introduces the tourists to a distinct expression of the Mughal era' and creates another spot of tourist attraction. The chief architect of the mosque was Ustad Khalil. Jama Masjid is familiarly known as - Masjid-i-Jahan Numa which quintessentially means ‘the mosque that commands a view of the world'. ‘ Jama' means Friday – the holy day for the Muslims and hence the name ‘ Jama Masjid' was coined.
