Tongkonan -: Torajan Kindred Houses - The most striking feature, perhaps, of Toraja is its houses. As you fly over Toraja, coming in via the South, you will see the small villages scattered in between the mountains covered with bamboo and veiled in mist. Most houses have the typical boat-shaped roofs, which, nowadays, are predominantly made of iron. The roofs used to be made of bamboo and other natural materials. The making of such a house was very laborious.
