Waiyapu is a traditional village (desa) on Sumba island, East Nusa Tenggara province, Indonesia.

[6] This island is the last place on Earth where some cultures still follow the traditions of the hill tribes of South-East Asia and commonly build megaliths such as dolmens for collective graves.

These tombs are more frequent in the west part of Sumba,[6] inhabited by segmentary societies made of clans and of politically autonomous villages.

In 2008, Anakalang prince Umbu Dingu ordered a 16-tons stone to cover the tomb of his father Reda Ana Buni.

The complete process of negotiations, extraction, paring, transport over some 5 kilometers (3.1 mi) and animal sacrifices, required some 4,000 persons and took two years to achieve.
