Kalawantin fort, or Muranjan fort in its present form, was built during Bahmani Sultanate to keep an eye on Panvel Fort and Kalyan Fort in North Konkan. Around 1458 AD, Malik Ahmad, the prime minister of the kingdom of Ahmednagar, took over the fort during his conquest of Konkan. After disintegration of Bahmani Sultanate, this fort remained with the Ahmadnagar Sultanate. During the collapse of the Ahmadnagar Sultanate, Shahaji tried helping them unsuccessfully against the separate forces of the Mughal Empireand the Adil Shahi dynasty and moved to Muranjan, along with wife Jijabai and younger son Shivaji for a brief period. However following Shahaji‘s defeat and agreement ofMahuli, North Konkan, along with this fort, was ceded to Mughals who granted ruling authority of the area to Adilshah of Bijapur. The fort was conquered by Shivaji from the Mughals in 1657, after he establishing himself in the Kalyan–Bhivandi area. At the time of the attack the fort was governed by Kesar Singh, a Mughal sardar, and was the only fort to put up a strong resistance. On seeing the signs of defeat the women in the fort performed Jauhar, a tradition of self-immolation to ensure an honorable and respectful death. Singh died during the battle in October 1657. Singh’s mother hid herself and her grandchild during the attack. Shivaji in an act of kindness made sure the lady and the child were allowed a safe passage out.
In the year 1826 Umaji Naik, a freedom fighter, and his associates are believed to have made this as their home for a brief period of time
