Torna Fort, also known as Prachandagad, is a large fort located in Pune district, in the Indian state of Maharashtra. It is historically significant because it was the first fort captured by Shivaji I in 1646, at the age of 16. The hill has an elevation of 1,403 metres (4,603 ft) above sea level, making it the highest hill-fort in the district. The name derives from Prachanda and gad.
