Q. Who built Sajra and Gojra forts near Vellore Fort?
Answer: Chhatrapati Shivaji Maharaj
Notes: Shivaji Maharaj built Sajra and Gojra forts near Vellore in 1678 during the siege of Vellore Fort. These hilltop forts were constructed to strategically bombard Vellore Fort, leading to Maratha control for the next 30 years. Their names mean "smart" and "cute" in Marathi.
