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. The word "tongkonan" comes from the Torajan tongkon ("to sit"). It is such a peaceful place to visit and de-stress and unwind. I like the shape of these houses very much.
