Pratapgad is a mountain fort located in Satara district, in the Western Indian state of Maharashtra.
The Maratha ruler Chhatrapati Shivaji Maharaj assigned Moropant Trimbak Pingle, his prime minister, to undertake the construction of this fort in order to defend the banks of the Nira and the Koyna rivers, and to defend the Par pass. It was completed in 1656.
The fort's historical significance is due to the Battle of Pratapgad, which took place here on 10 November 1659, between Chatrapati Shivaji Maharaj and Bijapur Sultanate general Afzal Khan. The fort was constructed on a hilltop, about 1,080 meters above sea level, with views of the surrounding landscapes. The fort has several watch towers and bastion for providing strategic military advantages during its time of use.
