Nagarjuna-sagar, or Vijayapuri, as it was earlier called is a small town located between Guntur and Hyderabad in Andhra Pradesh. The erstwhile name of the town means the city of victory while the present name is derived from Acharya Nagarjuna, a Buddhist saint.
The biggest attraction of the place is the Nagarjuna-Sagar dam. The dam, with a height of 124 metres, is the worlds tallest masonry dam. The dam was built in 1969, 14 years after its foundation stone was laid down by Pandit Jawahar Lal Nehru in 1955. The dam serves the irrigation needs of the region and is also a source of hydro-electricity.
Built on the River Krishna, the project was first called the Nandikonda project, after the name of the town which was located there. However, it was later changed to Nagarjuna-Sagar. The Nandikonda town has been shifted to the erstwhile northern part of Vijayapuri, now called the Hill Colony.
Hill Colony, along with Pylon Colony and Dakshin Vijayapuri are the three settlements of the town of Nagarjuna-Sagar.
Ruled by the Satvahanas and subsequently by the Ikshvaku rulers during ancient times, the town holds special importance for the state of Andhra Pradesh because of its hydro-electric power generation capabilities.
Steam boat rides are available to the dam where the turbines can be seen in action. Apart from the dam, there is the island of Nagarjuna Konda to see here. It is a scenic town on an artificial lake. There is also the Buddhist Museum in Nagarjuna-Konda which houses the various relics of the Buddhist saint, Acharya Nagarjuna, along with other important Buddhist information.
The town of Nagarjuna-Sagar lies very close to Mriyalguda and Machrela, which have the majority of the hotels of the region. The town is also very well connected with the cities of Hyderabad and Guntur through bus services.
