We examine the southern Vietnamese site of Rach Nui, dated to between 3390 and 3850 cal BP, in the context of three major aspects of the Neolithic in Mainland Southeast Asia: mound formation and chronology, construction techniques, and subsistence economy. Results indicate that this ca. 75 m in diameter, 5 m high mound, comprising over a dozen phases of earthen platforms, upon which were raised sophisticated wooden structures, was built in <200 years. While consuming domesticated millet, rice, and occasionally dogs and pigs, the main subsistence orientation included managed tubers and fruits and a range of mangrove ecosystem taxa: catfishes, turtles, crocodiles, monitor lizards, macaques and langurs, to name a few. This combined vegeculture-foraging lifeway in a mangrove forested environment, likely in the context of a tradable goods extractive industry, adds to a growing picture of significant diversity, and sophisticated construction skills in the Southeast Asian Neolithic.
Enormous thanks to the archaeologists and support team (Dang Ngoc Kinh, Le Hoang Phong, Nguyen Yen Hoang Linh, Bui Xuan Long, Van Ngoc Bich, and Do Thi Lan) involved in the Rach Nui project, including all local villagers. Further, the help and assistance of the Long An Provincial Museum was crucial to the success of this project: Director Bui Phat Diem and Deputy Director Vuong Thu Hong.
