The 4th and 5th Seasons of the Nubian Expedition of the Anuchin Research Institute and Museum of Anthropology, Lomonosov Moscow State University at the Sites of Deraheib and Onib (the Republic of Sudan). Part II. The Test Trench Near North-Western Wa

Introduction. During the fourth season of the Nubian Archaeological and Anthropological Expedition, organized by the Moscow State University Research Institute and the Museum of Anthropology, research was conducted in the Deraheib site in Sudan, from February to March 2022. A 2×2 m test trench with a depth of 2.2 m was opened during the season underneath the opening in the wall in order to clarify the structural features of the northwestern wall and determine the construction phases of the Fortress. Materials and methods. The excavated soil was meticulously sieved. The archaeological material consisted mainly of pottery and animal bones. Their analysis allows us to draw basic conclusions about the nature of the layer in which the trench was laid and to date the time of its formation. The light green soil was also analysed. Architectural analysis also allowed us to draw some important conclusions about the site. Conclusions. Based on the results of studies in the test trench and the data from the engineering and architectural survey of the Northern Fortress, we are able to propose a chronology for the early stages of its usage. We believe that the northwestern and northeastern walls built in the first construction phase were weakened by mudflows, and more powerful walls were built to reinforce them during the second construction phase. The northwestern wall from the second construction period was built on a layer of debris left from the first stage of fortress’s usage. This layer, consisting of lustre ware fragments, dates back to the 10th century. The space between the northwestern walls, which belonged to the first and second construction phases, respectively, i.e. the 10th and 11th centuries or possibly later, was used as a dump for household garbage, toilet waste, or even as an outhouse. © 2025.
