The Gunfoundry is located opposite the Mahboobia Girls School in a narrow lane. In fact, the whole locality is known as Gunfoundry.

It was one of the several cannon and cannonball factories set up in 1786 by the French General, Monsieur Raymond, who was in the service of the Nizam. One can still see specimens of the cannons and cannonballs manufactured in the Gunfoundry in the Public Gardens and various other places in Hyderabad, bearing inscriptions giving particulars of their manufacture. This is the only existing Gunfoundry as the rest were dismantled.
