Sawi people

The Sawi or Sawuy are a tribal people of Western New Guinea, Indonesia. They were known to be cannibalistic headhunters as recently as the 1950s.

Since then, many of the tribe have converted to Christianity and the world's largest circular building made strictly from un-milled poles was constructed in 1972 as a Christian meeting place by the Sawi. Christian missionary Don Richardson who lived among the Sawi wrote a book about the experience called Peace Child.
