Olorgesailie Prehistoric Site

Olorgesailie Prehistoric Site

Why Visit? Located in the southern Rift Valley, approximately 70 km south of Nairobi along the Magadi Road, the Olorgesailie Prehistoric Site is globally renowned for its abundant Acheulean handaxe discoveries and evidence of early human social and cognitive evolution. Set against the dramatic backdrop of Mt. Olorgesailie, this site represents over 1 million years of human prehistory and is part of a larger UNESCO-recognized fossil corridor.

Olorgesailie was first excavated by British archaeologists Mary and Louis Leakey in the 1940s, and later intensively studied by Glynn Isaac and a Smithsonian-led team. It remains a key site in understanding the Acheulean technological tradition, especially given the volume and variety of handaxes found in situ.

Stratified layers of sediment at the site provide a detailed record of climate change and human adaptation over hundreds of thousands of years. The site’s preservation is owed to volcanic ash that covered and protected it, enabling precise dating of its contents.
