Plain of Jars first site

Archaeologists believe that the jars were used 1,500–2,000 years ago, by an ancient Mon-Khmer race whose culture is now totally unknown. Most of the excavated material has been dated to around 500 BC–800 AD. Anthropologists and archeologists have theorized that the jars may have been used as funeral urns or perhaps storage for food.
Lao stories and legends claim that there was a race of giants who once inhabited the area. Local legend tells of an ancient king called Khun Cheung, who fought a long, victorious battle against his enemy. He supposedly created the jars to brew and store huge amounts of lao lao rice wine to celebrate his victory.
