Started in 1565, it took eight years and thirty-five lakh rupees to complete its construction and is second only to Taj in Agra. Qasim Khan Mir Barr-u-Bahr supervised the construction of this building.
One of the large fortified residences built at various strategic points of Mughal Empire; it had over five hundred buildings, as mentioned by Abul Fazal in his chronicles. Most of the buildings added later use marble as the chief construction material. At the time of Akbar, River Yamuna touched the fort and thus, a number of ghats were built here. Some of these ghats were meant to load and unload goods transported through river and other covered passages were for use by the harem inmates only.
