Torajan houses

In addition to elaborate funeral customs, Torajans are known for maintaining a caste-based society, where “blue-blood” members of the community demonstrate their status (and support the local economy) by building distinctive horn-shaped ceremonial houses called tongkonan. Traditional tongkonan are constructed without metal hardware, and are used to display the horns and jawbones of animals slaughtered in family ceremonies—also a sign of status. At least two water buffalo must be killed to consecrate a tongkonan itself.
