First discovered in 1977, the Karuo Relics Site is the only archaeological site of the Neolithic age discovered in Tibet. Covering an area of about 10,000 square meters, the Karuo site is one of three Tibetan aboriginal cultural relics and is the best-preserved evidence of ancient people living in the Qinghai-Tibet Plain. Archaeologists from home and abroad have unearthed dozens of house remains, two paved roads and tens of thousands of fragments of stoneware, pottery and bones from the site over the years. The Karuo site was listed as a major cultural relics site under state protection in 1996. It is an important glimpse into ancient Tibetan anthropological history and worth a visit, though transportation to the site and facilities at the site are fairly poor.
