The Plain of Jars is considered the most distinctive and enigmatic of all Laos attractions. The large area around Phonsavan, the main city of Xieng Khouang Province is dotted with stone jars but no one has a clear idea as to why they are there. The mysterious jars were carved from both sandstone and granite in various sizes from very small to about 3.5 metres high and are thought to be more than 2,000 years old. Legend has it that they were made to store rice wine while some believe they were for storing the dead. Until today the function of the jars is still disputed. The Plain Of Jars Highlights Of all the many jar sites, the three most popular ones to visit are known as Site 1, 2 and 3. The main reason is because they are safe from UXO (unexploded ordinance). Still, visitors are advised to walk only on the known routes as Laos is considered the most heavily bombed/mined country in the world. During the Vietnam War this area got hit hard and some of the bombs did not go off. Site 1 is where the biggest jar is located. While Site 2 and 3 offer picturesque views of farmlands and villages as they sit on top of small hills.
