is located between Amphoe Nang Rong and Amphoe Prakhkon Chai at the right-turn on Km.83-84 of Highway No.24 and twelve kilometers further on. The well-known Prasat Hin Pranom Rung is on the top of the Pranom Rung Mount. It is a walled-in enclosure, with both the door frames and walls carved in beautiful designs of Lopburi Period style with Khmer influence. It is thought that it was originally built as an idol temple according to Brahminic belief. Within the Prasat, or castle, is a throne hall built in the 12th century A.D. The beauty of the main prang of Phanom Rung lies not only in its plan, but in the vibrant stone carvings which cover large parts of the temple. Many lintels and pediments depict episodes from Indian texts such as the Ramayana, and the Puranas.
