'Buddhuni Konda' (The hill of Buddha) or Bojjana Konda as it has come to be known as, is a defunct, two thousand years old Buddhist monastry, located about an hour's drive from Visakhapatnam.
There are two hills, one being the Bojjana Konda, and the other nearby one called Lingala Konda, probably due to the hundreds of 'Shiv ling' like monoliths that dot the hill. However, these are not Shiv lings, but are rather stupas represtenting each monk that lived there and practised the Dharma.
The noteworthy features are the imposing Buddha carvings in the caves, the stupas - some of which are very large (supposedly belonging to the Mahayana tradition), and several hundreds of tiny stupas (which are attributed to the Theravada tradition). There are also several elevated platforms, on which the monks were said to have sat and meditated, hoping to attain Nirvana.
The heritage site is under the maintenance of Archeological Survey of India.
