Isimila Stone Age Site
Central Tanzania Region
The Isimila Stone Age Site, located about 16 kilometers south of Iringa town in Tanzania's Southern Highlands, is a prehistoric archaeological site dating back approximately 500,000 years. It is renowned for its abundant Acheulean stone tools, including handaxes, cleavers, picks, scrapers, and cores, which reflect the technological capabilities of early humans during the Middle Pleistocene. The site features a striking landscape of eroded sandstone pillars and canyons formed by rapid soil erosion, offering a unique geological and visual experience. Discovered in 1951 by an amateur archaeologist, Isimila quickly became a significant research focus after extensive excavations by University of Chicago scholars in the late 1950s. These excavations revealed a rich stratigraphic sequence and a vast collection of artifacts that have contributed greatly to understanding early human culture and technology in East Africa. The site sits at an elevation of about 1650 meters and is characterized by Precambrian crystalline metamorphic rocks, which early humans used as raw materials for tool production. Ongoing research emphasizes its conservation, geological formations, faunal remains, and stone tool technologies, making Isimila a vital window into prehistoric life and environmental changes during the Pleistocene epoch.

History
Isimila Stone Age Site was discovered in 1951 by D.A.
McCleman, an amateur archaeologist, who found the first stone artifacts and animal bones.
Following its discovery, the site attracted scholarly attention, notably from Prof Van Riet Lowe and Dr.
Louis Leakey.
Excavations by the University of Chicago in 1957-58 established Isimila as a key Middle Pleistocene archaeological site.
In 1957, it was gazetted as a reserved area under Tanganyika's Monument Preservation Ordinance and later became the first national historic site under Tanzania's Antiquities Act of 1964.
Research and excavation have continued intermittently up to 2017, maintaining its importance in understanding early human history in East Africa.
