Golconda Fort

This fort, originally built by the Kakatiyas, the rulers of the neighboring state, was made with mud. Later, the Shahis Golconda Fort converted it into a marvelous piece of architecture using advanced acoustics wherein sound signals could pass from the entrance of the fort to the top without the use of any electric gadgets. There is a sound and light show in the evening which is quiet popular.

The grand fortress is protected by three formidable lines of defense. The first, an outer fortification made up of granite blocks. The middle wall surrounds the base of the hill and the innermost one follows the contours of the highest ridge. The fort was famous for its great hoard of diamonds, mined nearby. The Kohinoor diamond was a celebrated jewel of the fort, now a part of the British Crown Jewels.
