Prasat Ku Pueai Noi, often referred to by locals as "Phra That Ku Thong," stands as the largest and most complete Khmer sanctuary in the upper northeastern region of Thailand. This historical treasure dates back to the 16th-17th Buddhist centuries, showcasing a magnificent blend of Baphuon and Angkor Wat architectural styles. The site was originally constructed as a Hindu religious complex dedicated to Lord Shiva, serving as a spiritual center for the community that once thrived along the ancient trade routes connecting the Khmer Empire to the Khorat Plateau.

The structural layout of the monument is meticulously planned, featuring three main brick stupas situated on a single high laterite base, all oriented towards the east to greet the rising sun. The central prang, the largest of the three, symbolizes Mount Meru, the center of the universe in Hindu cosmology. Surrounding these primary structures are "Bannalai," or library buildings, which were used to store sacred scriptures. The entire inner complex is enclosed by a rectangular laterite wall known as the "Kamphaeng Kaeo," which is further encircled by a "Baray," or a horseshoe-shaped holy moat, representing the primordial cosmic ocean.

The true highlight that draws historians and art lovers alike is the exquisite stone carvings. The lintels and pediments are remarkably well-preserved, featuring intricate depictions of Hindu deities and mythological scenes. One can witness the "Vishnu Reclining on the Naga" and various incarnations of Lord Krishna. The craftsmanship displayed in the deep-relief carvings on the sandstone blocks reveals the high level of artistic mastery of the ancient artisans, who managed to breathe life into the cold stone through fluid lines and expressive figures. Following extensive restoration by the Fine Arts Department using the anastylosis method, the sanctuary has regained its structural integrity, allowing visitors to walk through the corridors of time and experience the grandeur of an era where faith and art were inextricably linked.
