The Raigad Fort was built by Chhatrapati Shivaji Maharaj and the chief architect/engineer was Hiroji Indulkar. The main palace was constructed using wood, of which only the base pillars remain. The main fort ruins consist of the queen's quarters, six chambers, with each chamber having its own private restroom. In addition, ruins of three watch towers can be seen directly in front of the palace grounds out of which only two remain as the third one was destroyed during a bombardment. The Raigad Fort also has ruins of a market which was accessible to horseback riders. The fort also overlooks an artificial lake known as the Ganga Sagar Lake.
