A towering 11th-century citadel with a turbulent past, Golconda (meaning ‘round hill’) is admired for its unique architecture, gardens, palaces, military fortifications, magical acoustic system, ingenious water supply system, the famous “Rahban” cannon and an array of other attractions. Originally built by Kakatiyas in 1100 and later fortified by other invaders, Golconda Fort, now in ruins, represents a high point in Hyderabad’s history and is a must-visit archaeological treasure of India. Certainly one of the best tourist attractions in Hyderabad.
