A plateau in southern Sumatra with a series of impressive prehistoric megalithic monuments - massive slab graves and a rich collection of life-sized anthropomorphic carvings. The large stones are roughly carved into the shape of animals, such as the buffalo and elephant, and human figures - some with swords, helmets, and ornaments and some apparently carrying drums. They are stylistically similar to those of Iron Age burials of the last centuries BC, and remote connections with the Dong Son culture of northern Vietnam and the megalithic cultures of south India are likely.
