The Jal Mahal was built in 1591 AD by Shah Quli Khan, a member of the nobility of the Mughal empire and the governor of Narnaul.
The campaigns of Akbar to conquer northern India made Khan wealthy, and the commander distinguished himself by wounding the Suri general Hemu at the Second Battle of Panipat.
In gratitude for Khan's service, Akbar granted him titles, wealth, and appointed him as the governor of Narnaul.
[2] 15 years after completing his tomb, Khan began to construct a new palace in Narnaul; this structure became what is now the Jal Mahal.
[2] Khan began by creating a square artificial lake (often described as a tank or reservoir[2]) with an island in the center; this lake was intended to form a "second Kausar" (the Pond of Abundance in Muslim paradise) for the palace's occupants.
