Prasat Sa Kamphaeng Yai

Prasat Sa Kamphaeng Yai is a large 11th-century Khmer temple complex located in Sa Kamphaeng Yai Subdistrict, Uthumphon Phisai District, Sisaket Province, northeastern Thailand. Built in the Baphuon style during the Angkor period, it originally served as a Hindu shrine dedicated to Shiva and later became a Buddhist site. Notable for its three brick prangs, sandstone lintels, and laterite enclosure, it is one of the best-preserved Khmer monuments in Sisaket.

Visitors can expect a compact archaeological park with three central brick prangs on a laterite base, surrounded by a laterite wall and moat remnants. The site features carved sandstone lintels and pediments depicting Hindu deities, later Buddhist additions, and an active modern temple area adjacent to the ruins. The grounds are open and grassy with pathways around the main sanctuary, suitable for walking, photography and close viewing of Khmer architecture.
