Ku Phra Kona is a Khmer archaeological site located in Suvarnabhumi District, Roi Et Province. It holds historical significance as evidence of the Khmer civilization that once spread into the Mun–Chi river basin during the 11th–12th Buddhist centuries (approximately 16th–17th century CE).The site consists of a group of three brick prasats arranged in a north–south alignment on a single laterite base, reflecting religious concepts of the universe in Hindu–Buddhist Mahayana cosmology.The central prasat is the largest and was later modified to resemble a tiered base structure. It once served as a place for sacred objects, and today houses a replica of the Buddha’s footprint as a focal point of worship.The northern prasat is notable for its lintels and pediments, featuring a depiction of the reclining Vishnu (Narayana Anantasayin), an important Hindu motif symbolizing the creation of the universe.The southern prasat contains lintels and decorative motifs of celestial beings, reflecting beliefs in guardian deities protecting the sanctuary, and showcasing a blend of Baphuon-style Khmer art with local influences.

The entire structure was built using ancient fired bricks and laterite foundations, employing traditional Khmer masonry techniques where bricks are tightly fitted with minimal visible mortar, demonstrating highly skilled craftsmanship.Surrounding the complex were once important features such as a laterite enclosure wall, a naga bridge, and an ancient baray (reservoir), forming part of a sacred urban layout in Khmer cosmology.Today, the site is located within Wat Ku Phra Kona and continues to function as a religious site while also serving as a historical tourist attraction.

The area is also inhabited by large groups of crab-eating macaques, which have become a distinctive feature of the site, though visitors are advised to take care of their belongings.Ku Phra Kona thus serves as an archaeological site, a historical learning resource, and a living spiritual space where the present and the past coexist clearly.
