A stupa (literally “heap” or “pile”) is a reliquary, a shrine containing the remains of a holy or sainted person and/or artifacts (relics) associated with them, originating in India prior to the 5th century BCE as tombs of holy men and evolving afterwards into sacred sites dedicated to the Buddha (l. c. 563 - c. 483 BCE).
