Villages of Tana Toraja, Indonesia

Traditional Torajan tongkonan houses near Rantepao.
The most noticeable thing about Toraja are the many traditional houses, called tongkonan. Toraja is one of the few places in Indonesia where traditional structures continue to be built, other than for the benefit of tourists. The most distinctive feature of the houses is their saddle shaped roofs, with each end shooting high into the sky.
Legend ties the shape of the roofs to the origins of the Torajans. Their tradition is that they originated in the mountains of present-day Vietnam. Thousands of years ago, they began a voyage southward. After a couple of years island hopping south, they came to Sulwesi. They made their way by boat up the Sungai Sa'dan River as far as present day city of Enrekang, then continued to follow the river on foot to their present valley home. They bought their boats with them, and hung them between trees for shelter. From the shape of the boat supposedly comes the shape of the elaborate Torajan roofs, to remind them of their roots.
The roofs are made of arm-length sticks of bamboo split in half and stacked in an interlocking style very similar to terra cotta tile roofs the world over. Modern houses may have sheet-metal roofs, but they maintain the same shape, and even use carved wood panels on the under-side to mimic the shape of the traditional bamboo.
