The excavations showed that older wooden structures lay beneath the walls of the later brick Buddhist shrine. The layout of that more recent shrine duplicates the layout of the earlier wooden structures, pointing to a continuity of Buddhist worship at the site, Coningham says.
“The big debate has been about when the Buddha lived and now we have a shrine structure pointing to the sixth century B.C.,” Coningham says. The team used two kinds of scientific dating to find the age of the early shrine.
