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. They speak the Sawi language, which belongs to the Trans-New Guinea language family.
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.
