Prang Ku

Prang Ku is an 11th-century Khmer temple complex located in Ban Ku, Prang Ku Subdistrict, Prang Ku District, Sisaket Province, northeastern Thailand. The site features three brick prangs aligned north-south on a shared laterite base, surrounded by a U-shaped moat and laterite wall. Built during the Khmer Empire, it originally served as a Hindu shrine and later became a Buddhist site. It is notable for its well-preserved brickwork, lintels, and as the namesake of the district.

Visitors can expect a compact, open-air archaeological site with three brick prangs on a laterite platform facing east, enclosed by a laterite wall and moat. The central prang is the largest and best preserved. The grounds are grassy with scattered laterite and sandstone elements, lintels and colonnettes. Visitors can walk around the platform, view the prangs from outside, photograph the brickwork and surrounding moat, and explore the small compound at ground level.

Prang Ku is a Khmer sanctuary built in the 11th century during the Khmer Empire, generally attributed to the Baphuon style period. It consists of three brick prangs dedicated to Hindu deities, later adapted for Theravada Buddhist use. The laterite base, brick towers and sandstone decorative elements reflect Khmer construction techniques in northeastern Thailand. The site is registered as an ancient monument by the Fine Arts Department.

The temple reflects the spread of Khmer culture and Hindu-Buddhist religious traditions in Isan. It remains a respected local religious and community landmark and gives its name to the district and subdistrict. The site is used for cultural education and local merit-making activities.
