Hyder Ali took help of the French engineer who led the architecture and design of the fort and also helped in refurbishing the Upper fort of the Ballari. The lower side of the fort when completely constructed had a design alteration as the lower fort was at a lower height in comparison to other hills around which made the army positioned in the lower fort at a military disadvantage. Annoyed and buoyed by the design, Hyder Ali ordered the French architect to be hanged. The French architect’s grave is still found at the east gate of the fort.
