The Plain of Jars in the Xieng Khouang plain of Laos is one of the most enigmatic sights on Earth. The unusual scattering of thousands of megalithic jars across nearly one hundred sites deep in the mountains of northern Laos has fascinated archaeologists and scientists ever since their discovery in the 1930s.
How Were the Jars Constructed?
The unusual site known as the Plain of Jars is dated to the Iron Age (500 BC to 500 AD) and is made up of at least 3,000 giant stone jars up to three meters (9.8 feet) tall. Most are made of sandstone but there are others carved out of much harder granite and limestone. One of the big mysteries about the site is how the massive jars, some weighing up to 10 metric tons, were dragged from the quarry to be placed in groupings 10 km (6.2 miles) away.
