Nagarjunasagar is a massive irrigation project on the River Krishna located at a distance of about 150 kilometers from Hyderabad. Featuring a rich and interesting past, it was a valley in the Nallamala range of the Eastern Ghats with civilizations dating back to thousands of years. Recorded history, however, assigns the first signs to the later Satavahanas and subsequently the Ilkshvakus in the third century. The Sriparvata and Vijaypuri of yore were really temples where the famous savant and Bhuddist disciple Archarya Nagarjuna preached the message of the Buddha. These historic locations take its name from the Buddhist saint and scholar Acharya Nagarjuna who is said to have had set up a center of learning here.
Today, Nagarjuna Sagar is home to the Nagarjuna Sagar Dam - the World's tallest masonry dam irrigating over 10 lacs acres of land. It was during the building of this dam that the ruins of an ancient Buddhist civilization were excavated here. Some of the relics unearthed have been carefully preserved on a picturesque island called Nagarjuna Konda, located in the centre of a man-made lake. The vestiges of a sacred Buddhist stupa, vihara, monastries, a university and a sacrificial altar have been carefully reconstructed at Anupu on the east bank of this reservoir.
