Ta Kwai Castle is one of the significant historical sites in Surin Province, located in Ban Ta Kwai, Khok Takhian Subdistrict, Kap Choeng District, near the Thailand-Cambodia border. The castle reflects the artistic and religious influence of the Khmer Empire during the 11th12th centuries (Buddhist Era 1617). Its architecture follows the BaphuonAngkor Wat style, a period when the Khmer Empire expanded its power over what is now northeastern Thailand.
Origin and Historical Period
Ta Kwai Castle was built around the 11th - 12th centuries (Buddhist Era 1617), during the flourishing period of King Suryavarman I and King Suryavarman II of the Khmer Empire. The site is associated with Hinduism, specifically the Vaishnavism sect, and is believed to have been constructed to honor Lord Vishnu, serving as a spiritual center for the local community.
Due to its location near an ancient route connecting Angkor, Phimai, and other sites, Ta Kwai Castle played an important role in administration and in controlling the border areas of the Khmer Empire in the past.













Architecture and Decorative Motifs













The main sanctuary of Ta Kwai Castle is built from sandstone and laterite, situated on a rectangular base, with its entrance facing easta common feature in Khmer temple architecture. Within the castle grounds, traces of moats and surrounding walls can be seen, reflecting the Hindu cosmological concept of the universe.
Although much of the upper structure of the castle has collapsed, beautiful carvings can still be seen, such as the Kala face above the doorways, floral motifs, geometric patterns, and intricately decorated doorframe pillars. These are excellent examples of the BaphuonAngkor Wat style of Khmer art.
Meaning of the Name
"Ta Kwai"
The name "Ta Kwai" may have originated from the way local villagers referred to the site. In the local Thai dialect, "Ta" means an elderly man, while "Kwai" could refer to a persons name or an animal from local legends. Although there is no documentary evidence indicating the castles original Khmer name, the current name serves as a linguistic heritage, reflecting the close relationship between the community and the historical site.










Conservation and Contemporary Significance
Ta Kwai Castle has been registered as a national historical site by the Fine Arts Department. Partial excavations and restorations have been carried out to preserve its original structure. Today, it is open to the public and tourists, serving as a center for learning about the history, culture, and art of Southern Isan.
Beyond its artistic and religious value, Ta Kwai Castle provides tangible evidence of the Khmer Empires expansion into ancient Thai territories. It also reflects the historical urban planning, transportation networks, and border control systems of the time.
Although Ta Kwai Castle is not as large as Phimai or Phanom Rung temples, its simplicity and the enduring beauty of its carvings make it a cultural gem shining amidst the vast fields of Isan. The castle allows people today to reflect on their historical roots and connect closely with the grandeur of past civilizations.
