Torna Fort, Military fort in Pune district, India

Torna Fort, also called Prachandagad, is a hill fort in Pune district, Maharashtra, at 1,403 metres above sea level. Its dark stone ramparts follow the ridge, with a rounded bastion on one side and a lower crenellated parapet stepping down the crest. A compact flat-topped building crowns the summit, and a stone-lined pit holding dark water lies near the base of the walls.

In 1646, Shivaji Bhonsle captured this fortification at the age of 16, making it the first conquest on the path to founding the Maratha Empire. This early victory marked the start of a military campaign that reshaped the political landscape of western India.

The fort's name comes from Prachanda, Marathi for huge, and gad, fort; Shivaji renamed it Prachandagad after its size. The Menghai Devi temple, also called Tornaji temple, stands near the entrance. The fort is a trekking destination from September to December, after the south-west monsoon.

The trek to the fortification requires sturdy footwear and enough water, as the climb follows steep paths. Access begins from Velhe village, and the site opens from sunrise until 5:00 PM.

From the highest point, visitors can spot five other fortifications at once: Raigad, Lingana, Rajgad, Purandar, and Sinhagad dot the mountain range. This line of sight once allowed communication between sites using fire signals and drums.
