Xieng Khuang is very famous for its Plains of Jars. The jars are so huge that it can contain up to 2-3 persons inside. Until now, it remains mistery on how Xieng Khuang has these wonderful jars. There are 2 main hypotheses now on why these jars existed : it was used either for containing human body (burial) or for making wines. The jars dated as far as 4000 BC. It happened that some 6000 years ago Xieng Khuang area was a cross-road amidst wealthy trade routes (the silk road?) in Asia. The civilization in this area was so advanced that they created these huge jars for the unknown reason.
