Memot Rubber Plantation
Tbong Khmum [Tbong Khmŭm]
Memot Rubber Plantation is situated in eastern Cambodia's Tbong Khmum province and is notable for encompassing the Memot Circular Earthworks, a series of unique archaeological sites characterized by double circular embankments surrounding slightly curved inner platforms. These earthworks date back to approximately 2300-3000 BCE and provide insight into Neolithic communities that practiced rice cultivation, horticulture, and woodworking. The plantation's modern rubber trees grow atop these ancient sites, which have been studied since the 1960s, revealing tools such as adzes, axes, and ceramics locally produced using organic materials like rice husks. Despite the acidic red soil limiting organic preservation, the archaeological findings reflect small populations, likely fewer than 100 inhabitants, who left a minimal environmental footprint. The plantation thus represents a rare intersection of natural landscape and deep prehistoric cultural significance, inviting exploration of Cambodia’s distant past beneath its contemporary agricultural use.

Tip: Visitors interested in archaeology and natural landscapes should plan their visit during the dry season for easier access and visibility. Since many sites lie within working rubber plantations, arranging guided tours in advance is recommended to ensure access and respect for local land use. While entry fees or permits may apply, purchasing tickets ahead can help avoid delays. Visitors should also prepare for limited onsite facilities and bring adequate supplies for field exploration.
Interesting facts
- •The Memot Circular Earthworks consist of two concentric circular embankments enclosing a slightly curved inner platform, a rare architectural form in Southeast Asia.
- •Excavations have uncovered approximately 20,000 ceramic pieces, many tempered with organic materials like rice husks, indicating local pottery production.
- •Despite the acidic red soil that hampers organic preservation, lithic tools such as adzes and axes were found, suggesting woodworking and plot-clearing activities.
- •Population estimates for these sites are small, likely not exceeding 100 people, reflecting a low-impact Neolithic community.
- •The sites were first systematically recorded from aerial photographs in 1959, marking an early use of aerial archaeology in the region.
History
The Memot Circular Earthworks were first identified in 1959 by Louis Malleret through aerial photography along the Cambodia-Vietnam border.
Named "Memotien" culture by Bernard Philippe Groslier in 1962, these sites have been subject to intermittent archaeological excavations despite political unrest in Cambodia affecting consistent research.
Excavations by various scholars from the 1960s through early 2000s uncovered lithic tools and ceramics, confirming habitation during the Neolithic period around 2300-3000 BCE.
Over time, the sites have remained largely preserved beneath modern rubber plantations, which has both protected and obscured them from wider archaeological recognition.
