The Southern Mound of Konar Sandal, situated in the Halil River basin, is one of the most significant prehistoric sites in the Jiroft plain. Among the notable discoveries at this site is a life-sized clay relief positioned within a recessed, doorway-like feature in a large room. This relief, recognized as the oldest known example of a monumental clay relief integrated with architecture in the Middle East, dates back to the third millennium BCE. Since its discovery in 2006, its conservation has posed significant challenges for experts. The history of illegal excavations in the region and the lack of adequate infrastructure for permanent protection and maintenance of the site have exacerbated these challenges, leading to occasional proposals to transfer the artifact to a museum. The primary research question focuses on identifying an appropriate approach for the on-site conservation of the clay relief. Using both library-based research and fieldwork, this study gathered information related to the site and the relief, documented environmental factors contributing to its deterioration, and analyzed the data. The findings indicate that the current protective cover is inadequate. Environmental conditions, particularly moisture rising from the soil containing soluble salts, significantly accelerate the relief's erosion and the deterioration of its surface paint layers. Based on these findings, the study provides recommendations for optimizing the conservation of the relief.
