Bojjannakonda and Lingalakonda are two Buddhist rock-cut caves on adjacent hillocks, situated near a village called Sankaram, which is a few kilometres away from Anakapalle, Vishakhapatnam in the Indian state of Andhra Pradesh. The sites are believed to date between 4th and 9th Century A.D, when the 3 phases of Buddhism (Hinayana, Mahayana, and Vajrayana) flourished at Sankaram (Sangharam as it was called then) .
