Bavikonda was a hilltop Buddhist monastery near the coast north of Vizag that hosted up to 150 monks at a time, with the help of 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.
