Golconda fort, Hyderabad : One of the most magnificent fort complexes in India. Crenulated ramparts constructed of large masonary rocks surround the citadel, built on a 120 m high granite hill. The fort's accoustics are remarkable : the sound of hands clapping in the Grand Portico can be heard in the Durbar hall at the top of the hill. An hour long light and sound show is held daily except on Mondays. Kakatiya kings built the fort and ruled the nearby places. The fort is 11 km in perimeter and its walls are 4.5 to 5.5 m high. The whole fort is built of granite and flanked by 70 ramparts and eight huge gates. Previously the whole fort was surrounded by deep moat but slowly this was filled up.

About 8 km west of Hyderabad, the Golconda fort remained invincible for Emperor Aurangazeb despite his huge imperial army and seven months seige, but then he succeeded by stratagem and treachery. The Kohinoor diamond, which still adorns the British crown, came from here. Tomb of Qutb Shahi kings, a huge hollow tree are nearby and worth a visit.
