Shaniwarwada is an 18th-century fortification in the city of Pune in Maharashtra, India. Built in 1746, it was the seat of the Peshwa rulers of the Maratha Empire until 1818, when the Peshwas lost control to the East India Company after the Third Anglo-Maratha War. Following the rise of the Maratha Empire, the palace became the center of Indian politics in the 18th century.The fort itself was largely destroyed in 1828 by an unexplained fire, but the surviving structures are now maintained as a tourist site.ConstructionPeshwa Baji Rao I, prime minister to Chattrapati Shahu, king of the Maratha empire, laid the ceremonial foundation of his own residence on Saturday, January 10, 1730. It was named Shaniwarwada from the Marathi words Shaniwar (Saturday) and Wada (a general term for any residence complex). Teak was imported from the jungles of Junnar, stone was brought from the nearby quarries of Chinchwad, and Lime (mineral) was brought from the lime-belts of Jejuri. Shaniwarwada was completed in 1732, at a total cost of Rs. 16,110, a very large sum at the time.The opening ceremony was performed according to Hindu religious customs, on January 22, 1732, another Saturday chosen for being a particularly auspicious day.
