Hyderabad (/ˈhaɪdərəbæd/ HY-dər-ə-bad; ISO: Haidarābād, Telugu: [ˈɦaɪ̯daɾaːbaːd] , Urdu: [ˈɦɛːdəɾaːbaːd]) is the capital and largest city of the Indian state of Telangana. It occupies 650 km2 (250 sq mi) on the Deccan Plateau along the banks of the Musi River, in the northern part of Southern India. With an average altitude of 542 m (1,778 ft), much of Hyderabad is situated on hilly terrain around artificial lakes, including the Hussain Sagar lake, predating the city's founding, in the north of the city centre. According to the 2011 census of India, Hyderabad is the fourth-most populous city in India with a population of 6.9 million residents within the city limits, and has a population of 9.7 million residents in the metropolitan region, making it the sixth-most populous metropolitan area in India. With an output of US$ 95 billion, Hyderabad has the sixth-largest urban economy in India.
Until the 19th century, Hyderabad was known for the pearl industry and was nicknamed the "City of Pearls", and was the only trading centre for Golconda diamonds in the world. Many of the city's historical and traditional bazaars remain open. Hyderabad's central location between the Deccan Plateau and the Western Ghats, and industrialisation throughout the 20th century attracted major Indian research, manufacturing, educational and financial institutions. Since the 1990s, the city has emerged as an Indian hub of pharmaceuticals and biotechnology and information technology. The formation of the special economic zones of Hardware Park and HITEC City, dedicated to information technology, has encouraged leading multinationals to set up operations in Hyderabad.

The Qutub Shahi Tombs are located in the Ibrahim Bagh (garden precinct), close to the famous Golconda Fort in Hyderabad, India. They contain the tombs and mosques built by the various kings of the Qutub Shahi dynasty. The galleries of the smaller tombs are of a single storey while the larger ones are two-storied. In the centre of each tomb is a sarcophagus which overlies the actual burial vault in a crypt below. The domes were originally overlaid with blue and green tiles, of which only a few pieces now remain.
The complex was put by UNESCO on its "tentative list" to become a World Heritage Site in 2014, with others in the region, under the name Monuments and Forts of the Deccan Sultanate (despite there being a number of different sultanates). (Full article...)
