Prabalgad Fort, also known as Muranjan and Pradhangad, 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 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. Right next to Prabalgad, to its north, lies the steep Kalavanti (also known as Kalavantin) Fort. Prabalgad is often confused with Kalavati, but they are two separate forts.Prabalgad lies on the Prabal plateau between Matheran and Panvel and can be seen from the Mumbai-Pune Expressway. The Ulahas River runs to the east of the fort. The Gadhi River, and the Chanderi and Peb forts are to the west. To the south is the Patalganga River, and Manikgad and to the north is the Karnala fort.
Kelve Teen (also known as Kalavati, Kalavantin or Kalavantinicha Sulka) is a 685m high pinnacle on the northern edge of the Prabal plateau. It is located near the Machi and Vajepur villages. This is the site of the Kalavanti Fort.
