Purandar Fort (also called Purandhar Fort) figures repeatedly in the rising of Shivaji against the Adil Shahi Bijapur Sultanate and the Mughals. Purandhar fort stands 4,472 ft. above the sea (1,387 m) in the Western Ghats, 50 km southeast of Pune ahead of Saswad village. There are twin forts - Purandar and Vajragad (or Rudramal). The latter is the smaller of the two and is on the eastern side of the main fort. The village Purandar takes its name from this fort. Purandar fort is also known for birthplace of Sambhaji Raje Bhosale (second Chhatrapti and son of Chhatrapati Shivajiraje Bhosale)
