At this archaeological site, the three excavated holes are available for visitors interested in ancient history. Excavation hole 1 In each soil layer, there are buried skeletons by different burial features in each era. Skeletons buried at the lowest layer with 5.5 meters deep facing southeast, is in era 3,000. In era 2,000, burial facing the south was different from era 3,000. However, the similarity is burying the dead and their decorations as shell bracelets, beads, bronze rings, bronze bracelets, bronze head decorations, and earthenware together. The earthenwares were glazed red clay with a striped rope pattern, a narrow neck with a wide mouth, some are tall like a jug, some are spherical and short. The earthenware appearance changed to Phimai Black in era 1,500. They were black, polished, rough, and thin.
