General view of Golkonda Fort in Hyderabad on May 8, 2013 in Hyderabad, India. The Golkonda fort is one of India's renowned citadels, situated in Hyderabad, the capital of Andhra Pradesh state. According to most Indian historians, a mud fort was built in the 13th century by the Kakatiya dynasty after the ruling king heard about a shepherd boy having come across an idol on a rocky hill known as Mangalavaram. Three centuries later, the fort came into the possession of the Qutub Shahi dynasty, who expanded it into a massive fort of granite, extending around 5 km in circumference, before Mughal emperor Aurangzeb conquered it in 1687. The present complex comprises four distinct forts with a 10 km long outer wall with 87 semicircular bastions (some still mounted with cannons), eight gateways and four drawbridges, with a number of royal apartments, halls, temples, mosques and stables inside. The Golkonda fort is said to have had a vault where the famous Kohinoor and Hope diamonds were stored along with other diamonds.
