With the conquest of Golconda by Aurangzeb, the reign of the Qutb Shahi dynasty came to an end. Later, in the early 18th century, when Farrukh Siyar was the Mughal emperor, his subedar Mubrez Khan started the construction of a wall around the city of Hyderabad. A part of the wall was the already existing stretch built from Purana Pul to the Delhi Darwaza during the reign of Sultan Abul Hasan Tana Shah, the last Qutb Shahi ruler.
The wall around the city was completed only during the reign of Asaf Jah I, the first Nizam of Hyderabad.
At the time, the wall had 13 gates (the Delhi gate mentioned above was one of them), of which only two now remain:

Sadly, Hyderabad is no longer a walled city, as large stretches of the wall were washed away during the 1908 floods, and some of the darwazas became victims of modernization. But do check out this article with some really gorgeous photographs of walled cities around the world.
