Golconda Fort is situated on the Western outskirts of Hyderabad 11 kms west of the city. The fort built in the 13th century served the kings as a stronghold, administrative centre and market place.
Before the city of Hyderabad was founded the Deccan was ruled from Golconda fort. Founded originally by the Kakatiya's in the 13th century, the fort was taken over by the Bhaamani kings, subsequently passing to the Qutub Shahi Kings. The existing structure was expanded by the Qutub Shahi kings into a massive fort with granite walls and ramparts extending some 5-km in circumference over a period of 62 years.
The Fortress City within the walls was famous for the diamond trade and Ko-hi-noor diamond is said to have come from here. The name originates from the Telugu words "Golla" and "Konda" - 'Shepard's hill'. Famous features of Golconda includes its system of acoustics - a hand clap at a certain point below the dome at the entrance reverberates and can be heard clearly at the Bala Hissar, the highest point almost a kilometer away.
Golconda is also known for its Palaces, factories, water supply system and the famous Rahban cannon.
