Tsagaan Agui (White Cave)
Bayanhongor
Tsagaan Agui, located in the Gobi Desert of southwest-central Mongolia, is a significant Paleolithic cave site known for its stratified deposits and a calcium carbonate crystal-lined inner chamber. The cave has yielded abundant archaeological materials, some dating back approximately 700,000 years, making it one of the oldest known human occupation sites in the region. It comprises five distinct parts: the Entrance Terrace, Entrance Grotto, Main Chamber, Inner Chamber, and Lower Grotto. Excavations have revealed multiple sedimentation cycles reflecting changing climates from wetter, forested environments to drier steppe ecosystems. Archaeological finds include a variety of stone tools such as bifacially worked tools, Levallois-like flakes, scrapers, and bladelets, indicating evolving human technology over hundreds of thousands of years. Beyond its archaeological importance, Tsagaan Agui continues to hold cultural significance as a sporadic Buddhist pilgrimage destination. Since 1988, the cave has been under governmental protection, with ongoing research supported by international collaborations. Its unique combination of deep prehistoric heritage and spiritual relevance makes Tsagaan Agui a remarkable natural and cultural landmark.
