📍 LaosThe Plain of Jars
The Story
Across the Xieng Khouang plateau lie over 2,000 sandstone and granite jars weighing up to six tons each, some with lids carved as disks or animals. Local legend attributes them to a giant king. Excavations have found human remains nearby, suggesting burial or ritual use, but the civilization that carved and transported the jars remains unidentified.
