At the end of the fourth millennium BCE, the Omani Peninsula witnessed a significant cultural transformation, marked by the establishment of stable communities known collectively as “Magan.” This civilization maintained extensive trade and cultural relations with the civilizations of Mesopotamia, the Indus Valley, and Dilmun, highlighting Oman’s prominent role within the ancient exchange network. Archaeological surveys and excavations have revealed multiple sites, among which Bat, Al-Khutm, and Al-Ayn stand out as hosting concentrations of towers and distinctive tombs. The Bat and Al-Khutm sites comprise eight massive stone towers, with Al-Khutm Tower and Al-Rujum Tower being among the best-preserved. This study focuses on the architectural features of each tower while providing a comprehensive assessment of the condition of the aging and fractured stones and associated issues, including cracks, gaps, and erosion. The condition of the aging and fractured stones plays a crucial role in structural stability, as weakened stone cohesion leads to uneven load distribution, undermining the interlocking of the stone layers. For example, on the rear façade of Al-Rujum Tower, stone deterioration and fragmentation resulted in substantial collapses, exposing the internal structure. This demonstrates that stone weakness affects not only the surface but also the overall stability of the towers. The study also highlights advanced architectural techniques, such as the use of variable-sized stone blocks and deep wells for load distribution. Furthermore, the study documents restoration efforts. Al-Rujum Tower was restored long after excavation ended, whereas Al-Khutm Tower underwent restoration concurrently with the excavation campaign. By integrating the assessment of the condition of aging and fractured stones with architectural analysis, this study provides an in-depth understanding of construction techniques and the integrated economic and social systems of oasis communities in the third millennium BCE.
