Laang Spean (/ləˈæŋ spiən/; Khmer: ល្អាងស្ពាន, L’ang Spéan [lʔaːŋ spiən]; "Cave of Bridges") is a prehistoric cave site on top of a limestone hill (Phnom Teak Treang) in Battambang Province, north-western Cambodia. The site's name Cave of Bridges references the multiple limestone arches (or bridges) that remain after the partial collapse of the cave's vault. Excavations are still in progress, and at least three distinct levels of ancient human occupation have been documented. At the site's deepest layers, around 5 meters below the ground, primitive flaked stone tools were unearthed, dating back to around 71,000 years BP. Higher layers contain records of the Hoabinhian (11,000 to 5,000 years BP), whose stratigraphic and chronological context has yet to be defined. Future excavations at Laang Spean might help clarify the nature of the Hoabinhian and provide new data on the Pleistocene/Holocene transition in the region.
