The Plain of Jars are several plateaus in the province of Xieng Khouang in Laos. These enigmatic plains lie about 12 kilometers southeast of Phonsavan. Called by the locals Thong Hay Hin, they have been puzzling researchers since their discovery. In an area of approximately 25 hectares, you will find over 300 unique giant stone vessels and equally large lids, whose dimensions and weights amaze. There are several of these sites, which lie in a hilly savannah landscape, well over 1000 meters high. The scenery is characterized by numerous small and larger lakes, which are not all of the natural origins. Many of them are bomb craters that have slowly filled up with water.
The age of the jugs is estimated at 1500 to 2000, possibly even 2500 years. The weight is up to 6,000 kilograms. Archaeologists hold the vases for burial urns of a megalithic, proto-Malayan people, relatives of Lao Theung.
Since the Xieng Khouang Province was used by the US Air Force during the Vietnam War as a bombing zone for unused cluster bombs, many of the deposits are still inaccessible today. Only at sites 1, 2 and 3, a large part of the bombs was cleared. The walk-in areas are marked there.
