The Golconda fortress in Hyderabad is built on a granite hill that is 120 meter high, surrounded by massive battlements. Golconda Fort was first built by the Kakatiyas as part of their western defenses along the lines of the Kondapalli Fort. The fort finally fell into ruin in 1687, after an eight-month-long siege led to its fall at the hands of the Mughal emperor Aurangzeb.
