Tampang Allo's tau tau are some of the most impressive in Tana Toraja. Take a Kijang from Makale to Sangalla; get off about 1km after the turn-off to Suaya, and walk a short distance (less than 1km) through the rice fields to Tampangallo. The approach, following a small stream and rice paddies, is beautiful. You'll be greeted with a pile of skulls by the entrance.
The graves belong to the chiefs of Sangalla, descendants of the mythical divine being Tamborolangiq, who is believed to have introduced the caste system and death rituals into Torajan society.
