The sandstone pediment and lintel of Prasat Phra That Narai Cheng Weng showcase the Bapuan style of Khmer art. The pediment depicts "Shiva Nataraja" dancing within a glass-enclosed arch, while the lower lintel portrays Vishnu reclining on the serpent Ksheera Sagara (Ocean of Milk) amidst delicate floral motifs. This reflects Hindu beliefs and the remarkably well-preserved craftsmanship of ancient Khmer artisans in Sakon Nakhon province.
