The Fort, Agra c.1910 Publisher: Moorli Dhur & Sons Agra Fort was built in the year 1573 under the reign of Akbar – one of the greatest Mughal Emperors. It took more than 4000 workers and eight years of hardship to complete the fort. Knowing the significance of its location, Akbar built the fort to make it the main residence of the Mughals. The fort remained as the main residence of the emperors belonging to the Mughal dynasty until the year 1638. The fort houses numerous impressive structures like the Jahangir Mahal, Khas Mahal, Diwan-i-Khas, Diwan-i-Am, Machchhi Bhawan and Moti Masjid. In 1638, the capital of the Mughal dynasty was moved from Agra to Delhi, causing the Agra Fort to lose its status as the main residence of the Mughal emperors.
