The Plain of Jars is a series of archaeological sites in Laos. There are more than 90 sites with anywhere from 1 to 400 jars at each. No one really knows what they were used for. Scientists have theories and local legends are in abundance. The mysterious element drew me to the Plain of Jars initially. It proved to be much more educational and interesting than I initially thought, providing a valuable lesson on the UXO situation in Laos. Plain of Jars was one of my favorite sites in Laos.
