In Laos there is a place that has stumped archeologist for years. There are groups of huge stone jars all over the place and they cannot figure out what they were used for. Some say it was to store food and Lao Lao (whiskey) while others say they were for burial rituals. They may never know because there is no way of carbon dating them. It’s pretty cool!
From here I have taken the liberty to name them myself.
