The Baicheng Stone Disk Site refers to a location in China's Inner Mongolia region where hundreds of mysterious stone disks were allegedly discovered in a cave system. The reported disks are said to measure approximately 12 inches in diameter and feature spiral grooves containing hieroglyphic-like symbols. The site sits in the semi-arid landscape of northern China, approximately 100 kilometers from the border with Mongolia. While the exact cave location remains disputed, the region is known for its limestone formations and underground cavern systems that have preserved artifacts for millennia.
Estimated period when the stone disks were allegedly created, according to ancient astronaut theorists
First reported discovery of the stone disks by archaeologist Chi Pu Tei, though this account is disputed
Alleged translation of the disk symbols by Professor Tsum Um Nui, claiming they tell the story of the Dropa people and extraterrestrial visitors
Increased international attention and controversy surrounding the authenticity of the disks and their alleged government confiscation
The archaeological evidence for the Baicheng Stone Disks remains highly contentious within the scientific community. No peer-reviewed archaeological publication has documented the discovery or analysis of these artifacts, and attempts to locate the original disks have been unsuccessful. The supposed discoverer, Chi Pu Tei, cannot be verified in academic records, and Beijing University has no record of the alleged translator Professor Tsum Um Nui.
Skeptical researchers point out numerous inconsistencies in the disk story, including the lack of photographic evidence, missing museum records, and the absence of any corroborating archaeological context. The symbols allegedly found on the disks have never been subjected to legitimate linguistic analysis, and no examples of the supposed Dropa script have been found elsewhere in the archaeological record. Chinese archaeologists working in the region report no knowledge of such a discovery.
The scientific consensus treats the Baicheng Stone Disks as a modern fabrication or misinterpretation rather than genuine archaeological artifacts. However, the story has persisted in popular culture and continues to generate interest among alternative archaeology enthusiasts. Some researchers suggest the tale may have originated from misidentified bi disks—circular jade artifacts common in ancient Chinese culture—or from entirely fictional accounts that gained credibility through repetition.
What remains genuinely mysterious is the origin and motivation behind the disk story itself. Whether it began as deliberate hoax, cultural misunderstanding, or science fiction that was mistaken for fact, the Baicheng Stone Disk narrative demonstrates how archaeological claims can spread without proper scientific validation, highlighting the importance of peer review and evidence-based research in understanding our ancient past.
The alleged Dropa people described in connection with the disks are not recognized by any ethnographic studies of Chinese minority groups
Bi disks, circular jade artifacts with central holes, have been found throughout ancient China and may have inspired the stone disk legend
No photographs of the alleged disks have ever been authenticated by archaeological institutions
The story has inspired numerous science fiction novels and alternative history documentaries despite its disputed origins
The exact location of the alleged disk discovery remains unknown and disputed, making direct site visits impossible to arrange. The broader Baicheng region in Inner Mongolia is generally accessible to tourists, though visitors should check current travel restrictions and obtain necessary permits for the area.

If visiting the general Baicheng region, spring through early fall offers the most comfortable weather conditions, avoiding the harsh winter temperatures of northern China.
