Prasat Ta Kwai (also spelled “Prasat Ta Kuai” or “Ta Kwai Temple”) is an ancient stone temple located near the Thai-Cambodian border in Ban Chong Ta Kwai, Bak Dai Subdistrict, Phanom Dong Rak District, Surin Province, Thailand. It sits in the same archaeological zone as Prasat Ta Muen Thom and Prasat Ta Muen Tod, forming a cluster of ancient sanctuaries built along an old Khmer route that once connected Angkor to the northeast of present-day Thailand.
Due to its location on the undemarcated border, both Thailand and Cambodia claim sovereignty over the site, which has led to tensions and armed conflict in the past and even more recently in 2025.
Legacy of the Khmer Empire in Southeast Asia
Prasat Ta Kwai was constructed during the 11th–12th centuries CE, a period associated with King Suryavarman II of the ancient Khmer Empire (builder of Angkor Wat). The temple was dedicated to the Hindu god Shiva, and follows the Bayon architectural style, popular during the reign of King Jayavarman VII.
The sanctuary features a small laterite base, sandstone carvings, and was originally a Hindu shrine. A lingam (phallic symbol of Shiva) was once installed in the central chamber.
Strategically, the temple was part of the ancient Khmer road system, serving as a religious rest stop or guard postbetween the Angkor heartland and outlying settlements in what is now northeastern Thailand.

Prasat Ta Kwai is part of a cluster of three temples:
Prasat Ta Muen Thom: The largest temple in the group, located in what is now disputed territory. It features detailed carvings, a central sanctuary, and was likely used for royal rituals.
Prasat Ta Muen Tod: A smaller sanctuary nearby, believed to have served as a resting place or hermitage for ascetics.
Prasat Ta Kwai: Strategically located and smaller in scale, this temple became a flashpoint in modern border disputes due to its location and historical value.
The Longstanding Dispute Over a Sacred Site
Although Prasat Ta Kwai is physically located inside Thai territory according to many modern maps, Cambodia maintains a claim over the site, citing historical continuity from the Khmer Empire. The border line in this mountainous area was never clearly demarcated, giving rise to a “grey zone” that both countries seek to control.
Between 1998 and 2011, there were multiple armed skirmishes in this region, especially involving Prasat Ta Muen Thom, with artillery shelling, land mine deployment, and diplomatic tension reaching international forums like UNESCO and the International Court of Justice (ICJ).
In July 2025, the area around Prasat Ta Kwai again became the site of armed conflict between Thai and Cambodian forces. Here is a timeline of recent events:
Date (2025) / Event
July 21 / Aerial engagement by Thai aircraft near the disputed zone
July 22 / Reports confirm 3 Thai soldiers killed and 1 wounded in BM-21 rocket attack
July 23 / Cambodian sources claim they have secured control of Prasat Ta Kwai
July 24–26 / Thailand holds emergency national security meetings; refrains from escalation
July 26 / Social media nationalism surges on both sides; online campaigns intensify
According to reports by Thai Post, Bangkok Biz News, and Reuters, Cambodian military forces have raised their flag in the area surrounding Prasat Ta Kwai and declared de facto control. Thai military sources, however, have not officially acknowledged the loss, though they reportedly withdrew from certain hotspots to avoid civilian casualties and damage to cultural sites.
Prasat Ta Kwai is more than an ancient ruin. It has become a symbol of national pride and territorial integrity for both nations. Here’s why it matters:
Strategic Location: Situated along the Dongrak mountain range, the temple provides a vantage point over a key military corridor.
Cultural Legacy: Both countries claim ancestral and spiritual ties to the Khmer civilization.
Undefined Border: The lack of clearly marked borders makes it a legal and diplomatic powder keg.
Nationalist Sentiment: Leaders on both sides use the temple to rally domestic support during political crises.
Prasat Ta Kwai is located in Surin Province, Thailand, but its proximity to the Cambodian border has made it a subject of dispute.
The temple was built during the Khmer Empire (11th–12th centuries) as a Hindu shrine dedicated to Lord Shiva.
Both Thailand and Cambodia claim ownership, and the site has seen repeated military conflict.
As of July 2025, Cambodia claims to have control of the area, though the Thai government has not officially conceded.
The issue remains unresolved and could require intervention from international organizations.
