Prabalgad Fort is located between Matheran and Panvel in the Indian state of Maharashtra, at an elevation of 2300 feet in the Western Ghats. It was built on a plateau very close to Matheran, but unlike Matheran it does not have a good source of water. It was known as Muranjan until it was taken over and renamed by the Maratha forces under Shivaji’s rule. The fort contains a temple to Ganesh and some stone ruins. Its sister fort is Irshalgad.
