The Golconda fort is a fine example of magnificent architecture. The fort was renowned for its diamond trade and it is said that the world famous "Kohinoor" diamond was found here. The architecture of the fort is such that a mere clap at the entrance could be used as a distress signal thus alerting others of any unseen dangers. The technique that was used was of advanced acoustics. The clever architectural plan also allowed uninterrupted supply of water throughout the year. The fort had sprawling gardens and dancing fountains, which are now in ruins.
The fort is built on a granite hill at a height of around 120 meters and is bordered by thick walls. The stone blocks used for constructing these massive walls weigh several tons. The structure is such that though closed, it allows much space for all over ventilation, thus allowing circulation of cool breeze that provides respite from the summer heat.
The entrance gates of the fort are colossal and are fitted with iron spikes to thwart elephants from damaging them. The entire township of Golconda is surrounded by an outer wall, which is about 11 kilometers long. This long road used to be a busy market in the by gone where one could get stuff like jewellery, diamonds, pearls and other gems.
