Prasat Phakho, also known as Prang Phakho, is a historical and archaeological site dating back to the Khmer Empire, located in Chok Chai District, Nakhon Ratchasima Province. The primary materials used in its construction were brick and sandstone, with an architectural style indicative of the Khmer art period around the 16th Buddhist century (approximately 1,000 years ago), a period when many large temples were built across the Northeast of Thailand (Isan). The sanctuary complex consists of a principal prang (tower) constructed of brick, set upon a laterite and sandstone base. It is oriented towards the east, adhering to the traditional mandala and Hindu beliefs, to receive the morning sun. The complex also included subsidiary buildings, or bannalai (libraries), flanking the main tower (originally believed to have consisted of three structures, two of which have clearly defined remains today). This temple signifies the extensive influence of Khmer culture in the region, and it is hypothesized that it was built as a devasthana (temple) dedicated to the worship of Shiva or another Hindu deity, serving as a spiritual focal point for the ancient community.

A distinct physical characteristic of Prasat Phakho is its layout, which is encircled by a large moat shaped like a U or a horseshoe, leaving the front of the sanctuary open. This particular feature is a compelling aspect of Khmer temple construction found in certain complexes in the Southern Isan region. Archaeological excavations at the site have yielded significant evidence, notably the exquisitely carved sandstone lintel. In particular, a lintel depicting Indra seated atop Erawan (Airavata), the elephant, was discovered. This piece of art is a crucial artifact for dating and defining the artistic style of the temple. The lintel not only reflects the refined craftsmanship of the era but also suggests the high status of the sanctuary. Although much of the structure now remains only as the base and the brick cella (main chamber), it retains the grandeur of Khmer architecture and remains a vital piece of historical evidence linking Nakhon Ratchasima to the ancient Khmer civilization.

Currently managed and conserved by the Fine Arts Department, Prasat Phakho serves as an important educational resource, open to visitors and scholars interested in studying the ancient civilizations of the area.
