Rajgad, as the name suggests, its Royal Fort. Shivaji reign was handed all over from Rajgad as it was earlier the capital of Maratha Empire - the Hindavi Swaraj till he became Chhatrapati, after which he shifted it to Raigad, post Coronation. It is one of the majestic fort of the Sahyadris. Rajgad was formerly known as Murumbdev, as it is built on the hill called 'Murumbdevacha Dongar' [मुरुंबदेवाचा डोंगर]. It is an incarnation of high class architecture of the great Maratha Chhatrapati Shivaji Maharaj. 

This fort has witnessed many historic events like the birth of Shivaji's son Rajaram, the death of Shivaji's wife Saibai, the burial of Afzal Khan's head in Mahadarwaja walls of Ballekilla, the return of the King from Agra and many more. This fort was one of the 12 forts that Shivaji kept when signing the treaty of Purandar (1665) with the Rajput King Jai Singh who was leading the Mughal forces.  Under this treaty, 22 other forts were handed over to the Mughals, which were later conquered back.
