Golkonda Fort
Located in the capital city of Hyderabad, the fort was first built of mud by Kakatiya rulers during the 13th century. However, it gained glory under the Qutub Shahi dynasty. The world renowned Kohinoor diamond was found here. An added attraction here are the enchanting sound & light show in the evenings. One of the most interesting features of the Golconda Fort is its system of acoustics. The sounds of hands clapped at the entry gate can be heard clearly at 'Bala Hissar', the highest point, a kilometre away.
