Near some villages around Tana Toraja, you'll see small fields of stones pointing straight out of the ground. These are called rante, and the stones are in effect memorials to important people of the past. These ceremonial sites are sometimes used for funerals and other important events for the Toraja.
A rante, or memorial stone ceremonial ground
The most impressive rante is probably at Bori, north or Rantepao. There are also some interesting boulder graves as well as some trees with infant tombs in them nearby. There's a small admission charge.
