Torajans are renowned for their massive peaked-roof traditional houses known as tongkonan (the buildings in the picture).
Kete' Kesu, the village in the picture, is one of the oldest Toraja's villages.
Tongkonan are the traditional Torajan ancestral houses. They stand high on wooden piles, topped with a layered split-bamboo roof shaped in a sweeping curved arc, and they are incised with red, black, and yellow detailed wood carvings on the exterior walls.
Before the 20th century, Torajans lived in autonomous villages, where they practised animism and were relatively untouched by the outside world.
