This volume presents the results of the 2020 season excavations conducted by the Georgian National Museum at the multi-layered settlement of Irmis Rka, located in the Samtskhe-Javakheti province in southwest Georgia. Excavations on the site have confirmed the presence of pits and domestic architecture from the Early Bronze Age Kura-Araxes Culture, as well as deposits of the subsequent Bedeni Culture, along with abundant related materials. The site reveals signs of occupation during the Late Bronze-Early Iron Age, with evidence of fortification and various artefacts. Additionally, medieval activities have been documented. The site demonstrates the full evolution of the Kura-Araxes tradition, offering perspectives to illustrate its gradual changes and development. One of the site's most significant aspects is the presence of the Bedeni culture, marking its first appearance in this area. While excavations at Irmis Rka are ongoing, the results presented here contribute new data to a wide range of discussions.
