Old is gold! Golkonda Fort is 10 km west of Hyderabad city. This fort was meant for defence hence one will find not much of the finespun intricate architecture like the northern Indian forts. Golkonda Fort was one of the reasons of the downfall of Aurangzeb. I ain't a history scholar, you can always google its history for further reference hehe
Golkonda Fort is built on a 400-ft. high hill, its highest point occupied by a double-storeyed structure, originally called Tana Shahi ki Gaddi. It is now known as Bala Hisar, which is the inner area marked for palaces. One of the most magnificent fort complexes in the country, Golkonda, meaning shepherd hill, was built consecutively by three dynasties, the Kakatiyas, the Bahmanis and the Qutub Shahis, the major contribution coming from the latter. It betrays the confluence of Hindu and Muslim architectural perceptions of the times. It was the capital of the Bahmani kings first and the Qutub Shahis later for sometime, before they shifted the capital to what is now the old city of Hyderabad. Legend has it that Golkonda was the centre of a flourishing trade in diamonds and that the world-famous Kohinoor diamond came from this market.
