Bavikonda Telangana & Andhra Pradesh

Bavikonda was a hilltop Buddhist monastery with massive rainwater tanks and a natural well. It flourished from around the 3rd century BC to the 3rd century AD, and has special importance because a relic vessel found within its biggest stupa, the Mahachaitya, contained a piece of bone believed to be from the Buddha himself. It's 37km north of Visakhapatnam.
