KALAVANTIN DURG

Kalavantin Durg is a 686 meters high summit located in the Western Ghats, near the Prabalgad fort in the Raigad district of Maharashtra, India. It is a popular trekking destination.
It is also known as Kelve Teen, Kalavantinicha Sulka, or Kalavantin Pinnacle; alternative transliterations include Kalawantin, Kalavati, and Kalavanti.
There is a series of steps leading to the top of the pinnacle, but little is known about the history of the structure. According to local guides, it was built for a queen called Kalavantin in the 15th century, around the same time as the neighbouring Prabalgad.
In Marathi language the word "Durg" means fort. Although it is called "Kalavantin Durg", there is no fort. Kalavantin is a pinnacle which was used by the ruler to have watch on surrounding area.
