Explanation: Built by Shah Jahan’s son and successor Aurangzeb (ruled 1658-1707), the Badshahi Mosque was the largest mosque in the world when completed in 1673. It lost the title of the world’s largest mosque in 1983, however, it remains one of the top 10 largest mosques in the world. Its style is reminiscent to that of Jama Masjid in Delhi but it is much larger as it has a capacity for 100,000 people.
