Deeg was the first capital of the Jat People with Badam singh as its ruler in 1722. He was responsible for constructing the royal palace on the southern side of the garden, now called Purana Mahal. Near Bharatpur bird sanctuary in Rajasthan lies another extraordinary tourist complex, consisting of a mini lake, a palace, a fort, and an intricate fountain system. The rustic palce does not have the romantic lure of Udaipaur or Jaipur. In 1730, crown prince Surajmal was reported to have errected the strong fortress with towering walls and a deep water moat with high ramparts about 6 metres wide in the southern portion of the town. Although the Surajmal shifted his capital to Bharatpur, he lavished attention on Deeg. He built elegant palaces in the form of a quadrangle.

At its cenre is a well laid garden with walkways, decorative flowerbeds, shrubs, trees and numerous fountains, which keep the place cool. The building to the north is called Nand Bhavan. One of the palaces Suraj Bhawan, is built entirely of marble and is ornamented with stones of different colours. Another palace built with grey stone is called Kishan Bhawan. A massive water tank on the terrace of Kishan Bhawan feeds the fountain in the middle of the garden. The gigantic water tank is capable of holding 6 to 7 lakh gallons of water.

This garden citadel at Deeg is strictly Mughal in its layout and style. An atmosphere of mystery and romance pervades the whole place. The beautful marble swing of Gopal Bhawan is a war trophy brought from the Mughal court at Delhi by Raja Surajmal. Deeg is well connected by road with Alwar, Bharatpur and Mathura.
