Lakhon (also spelled Lochoen in early European records) is an abandoned historical city located along the Mekong River near present-day Thakhek in Khammouane Province, Laos.^[1][2] The site lies in the middle Mekong region and is associated with the area surrounding Vat Sikhottabong, an important Buddhist temple complex. Archaeological surveys have revealed the remains of numerous religious structures and habitation areas, indicating that Lakhon was once a significant urban center along the river.^[2]

Historical accounts suggest that Lakhon functioned as a major commercial hub in the middle Mekong during the early modern period.^[2] In the 17th century, the Dutch merchant Gerrit van Wuysthoff recorded a settlement called Lochoen while traveling through the region as part of a trading expedition from the Dutch East India Company. His description portrays the city as a prosperous settlement with many temples and active trade connections along the Mekong.^[1]

Modern archaeological work has confirmed that the area surrounding Vat Sikhottabong preserves a large archaeological landscape with dozens of brick mounds, ruined stupas, and scattered architectural remains. These findings support the interpretation that Lakhon was an important religious and commercial center in the Mekong corridor prior to its abandonment.

The archaeological remains of Lakhon were surveyed as part of the Middle Mekong Archaeological Project led by researchers from the University of Pennsylvania Museum. Field investigations around Vat Sikhottabong documented more than one hundred visible archaeological features, including brick foundations, collapsed stupas, and sculptural fragments distributed across the surrounding terrain.^[2]

Because most domestic structures in the region were historically constructed from wood or bamboo, few residential buildings have survived. The majority of visible remains are therefore religious structures built from more durable materials such as brick or stone, suggesting that the surviving archaeological landscape largely reflects the city’s ritual and religious architecture.^[2]

Ceramic fragments collected from the site indicate that Lakhon was occupied between approximately the 14th and 18th centuries. Among the materials identified are imported ceramics, including Japanese wares, which suggest that the settlement participated in regional and international trade networks.^[2]

Its position along the Mekong River likely allowed the city to serve as an intermediary trading point between inland mainland Southeast Asia and maritime trade routes. The presence of imported ceramics and other artifacts supports the view that the city was connected to broader commercial exchanges across the region.^[2]

The precise reasons for Lakhon’s abandonment remain uncertain. Some scholars have suggested that regional political instability in the late 18th and early 19th centuries may have contributed to the city’s decline.^[2]

One possible factor was the series of conflicts involving the Lao kingdoms and Siam during this period. Military campaigns and the forced relocation of populations in the Mekong region may have led to the depopulation of settlements such as Lakhon, leaving the city to gradually fall into ruin.^[2]
