1942-1944 Excavations

Archaeological Discoveries

Louis Malleret's excavations revealed a cosmopolitan ancient city with artifacts from Rome, China, India, and Persia.

Discovery & Excavation

Excavation at Óc Eo began on February 10, 1942, after French archaeologists discovered the site through aerial photography. Using these images, Louis Malleret identified the outlines of an ancient city with a dense network of canals, reservoirs, temples, and building foundations.

Malleret conducted the first systematic excavations in 1944 at the foot of Ba The mountain in Thoại Sơn district, An Giang province. His four-volume work L'archéologie du delta du Mékong (1959-1962) remains the foundational study.

Evidence of Roman Trade

Roman Golden Medallions

Among the most remarkable finds were golden medallions from the reigns of Antoninus Pius (138-161 CE) and Marcus Aurelius (161-180 CE). These Roman emperors were associated with the embassy to China in 166 CE.

These medallions, now in the Museum of Vietnamese History in Hồ Chí Minh City, provide tangible evidence of Rome's far-reaching trade networks—supporting Pliny's complaint about the "drain of Roman gold" to the East.

A.H. Christie (1979) noted these Roman objects added weight to the identification of Kattigara with Óc Eo.
