Plain of Jars is an archeological site where clusters of unusual pots carved out of stone have been found. These pots, also called Jars, were most likely used in funeral ceremonies. They were made in the period from 500 BC to 200 AD. There are 90 groups of jars, jar fragments, and lids, in total 2500 items. Since this region was subjected to "carpet bombing" during the wars in Indochina, and only nine groups of jars were cleared of the remaining explosive devices, a visit in the presence of a local guide is a wise decision.
