Situated in Amphoe Ban Phue, this archeological site features a large number of ancient ruins and objects dating from prehistory. They are mostly from the Dvaravati, Lop Buri, and Lan Xang periods. The site is located in a lush forest called Pa Khua Nam. Within are many rocks of peculiar shapes, the result of a slow-moving glacier millions of years ago. Many of the ruins and objects found in the area were made from the materials found locally, and were not built entirely by hand-for instance, a rock decorated as a stupa, or chiseled into the shape of a foot. Pre-historic cave paintings, sandstone images and idols, and more are interesting sights to behold. The site was declared a Historical park by the Fine Arts Department in 1991.
