 The "tongkonan" at Ke'te' Kesu' is reputed to be 500 years old; too old to trace a direct descendant from the founder to maintain the title that goes with the house.The buildings themselves, however, are constantly maintained and renewed, thus this age refers to the length of time years for which that particular site has been used as a meeting place.Common to Toraja of all religions is the cultural centrality of the "tongkonan" as ancestral homes.
