The Ho Tre archaeological site in Hoa Tay village was discovered by The Phuc La and Thi Tuat Luong in a field trip during the 2018 dry season. The cultural relics are mainly distributed on the crater surface of the Ho Tre volcano with the average altitude of about 578 m asl. Hundreds of artefacts have been collected, including such stone tools as: oval axes, grind-stones, sharpening stones, stone cores, flakes, ect., which are mainly made of basalt, quartzite silty-sandstone, silty-sand stone, hornfels; and several broken pieces of pottery. According to the initial archaeological assessment, their technique and geometric features characterise for the Neolithic Age. The finding has a great significance, contributing to adding research materials about the Neolithic Age in the south of the Central Highlands in particular and in Vietnam in general as well.
