History: This fort dates back to Buddhist time. After Yadav, Bahamani, it was ruled by Nizamshahi. Shahaji Maharaj, Rajmata Jijabai and Chhtrapati Shivaji Maharaj have stayed on the fort. After the fall of Nizamshahi, it was taken over by Adilshahi and later by Mughals.
In 1657, fort was won by Marathas. As per the treaty of Purandar, it was handed over to Mughals. After the treaty was broken, Marathas took it back. In 1818, Britishers won this fort and destroyed it a lot.
Prabalgad is a vast fort in Matheran range. It is located on a big plateau. Kalavantin is not a fort, a pinnacle located on the northern side of the fort. It could have been used as a watchtower.
Kalavantin is notorious for taking many lives. There have been many incidents where people have lost their lives while visiting this peak. That is why it is very important to stay safe. Make sure you are not going alone. Sharp edges, strong winds, narrow steps, and the phobia of height will make the matter worse. Do NOT go here in rainy season unless you have a trek leader, low visibility and slippery path will be tough to handle.
