Golconda fort located in Hyderabad, India was an important trade center for diamonds in the region. It was originally constructed in 1200 as a mud fort and was home to various rulers over time, notably the Qutubshahi Sultans from 1518 to 1687. The fort has thick defensive walls with 87 bastions and 9 large gates. It also contains gardens, factories, fields, and water storage systems. Golconda fort was very difficult to attack due to its strong security features like a deep ditch along the walls and soldiers stationed in lookout points.
