Prasat Non Ku is a small but historically and archaeologically significant ancient site, located in Ban Non Ku, Tambon Than Prasat, Non Sung District, Nakhon Ratchasima Province. This area was once a major center of Khmer civilization in the lower northeastern region (Isan). It is estimated that this monument was constructed around the 16th Buddhist century or roughly the early Baphuon period of the Khmer Empire. This pre-dates the construction of the larger Prasat Hin Phimai and serves as crucial evidence demonstrating the expansion and influence of Khmer culture in the region.

Layout and Structure: The Non Ku temple complex consists of five main structures built on the same laterite base, facing east.

• Prasat Prathan (Main Towers): There were three main towers constructed from brick, aligned north-to-south. Currently, only the base and the lower sections of the walls remain. The bases of the prasats display the delicate craftsmanship of ancient Khmer architecture.

• Bannalai (Libraries): Two smaller buildings constructed from sandstone are located in front of the main towers to the east. These libraries served as repositories for sacred religious texts (Tripitaka or Vedas). The presence of the sandstone structures helps pinpoint the architectural style of that specific era.

Artifacts and Belief System: Archaeological evidence recovered from the site suggests that Prasat Non Ku was a Hindu religious sanctuary of the Shaivite sect, dedicated to the worship of Lord Shiva. Key artifacts discovered in the vicinity include:

• Sandstone Lintel Fragments: Pieces of lintels were found, carved with religious narratives, notably imagery believed to depict Shiva, characteristic of the Khmer Baphuon style.

• Deva Heads and Sculpture Fragments: Various heads of deities and other sculptural fragments were found. These pieces were likely used to adorn the temple towers and libraries, reflecting the past splendor and the skill of the artisans.

Significance: Prasat Non Ku plays a vital role in connecting the region's history by providing physical evidence of an early settlement and a center of religious belief preceding the establishment of larger cities like Phimai. The site is currently registered as an ancient monument by the Fine Arts Department and is located within the grounds of Wat Non Ku, making it easily accessible for visitation and historical study.
