Geophysical Prospection of the South-Western Quarter of the Hellenistic Capital Artaxata in the Ararat Plain (Lusarat, Ararat Province, Armenia): The South-West Quarter, City Walls and an Early Christian Church

Abstract This study presents the findings of the 2024 geophysical prospection campaign conducted within the south-western Lower City of the Hellenistic capital Artaxata, situated in the Ararat plain, Armenia. Using advanced magnetic survey techniques, we sought to investigate the urban layout and expansion of the ancient city. The campaign aimed to test hypotheses derived from aerial imagery regarding the existence of city walls in this area, a previously undocumented feature for the Lower City. Spanning approximately 20 ha, the survey revealed an array of archaeological features, including wall structures, ditches, and pits, alongside evidence of domestic and craft activities such as fireplaces. Notably, the findings confirmed the presence of the south-western city walls, delineating a settlement area larger than previously known. Additional discoveries include monumental architectural remains, such as an octagonal structure potentially associated with an early Christian church. However, the interpretation of these structures, including their chronology and function, remains tentative pending further excavation. These results not only extend our understanding of the city’s urban development but also highlight the efficacy of integrating geophysical surveys with archaeological methods in reconstructing historical urban landscapes. Future investigations will focus on resolving ambiguities through targeted excavation and refining interpretations of the magnetic anomalies observed.
