The name Irshalgad itself is a misnomer; Irshal is not a fort but actually a pinnacle. This is the reason why it hardly figures anywhere in history. Shivaji Maharaj captured the complete region of Kalyan and Bhiwandi, up to Rairi in May 1666. This fort too, must have come under the Maratha rule at that time.
Chowk village is birth place of Netaji Palkar who was a close associate of Chhatrapati Shivaji Maharaj.
Here is some info abt the fort:
Height: 3700 feet above MSL (Approx)
Base Village: Chowk -Irshalwadi
