Bisya is one of the most important archaeological areas in the Oman peninsula where the development of the first sedentary sites may be observed. The French Archaeological Mission in Central Oman investigates monumental architecture, organized settlements and funerary structures from the Early Bronze Age through survey and excavations. This paper presents the results of two seasons of fieldwork at Bisya (ad-Dakhiliyah, Oman) in 2022-2023. The regional survey evidences the extension and organisation of the EBA occupation in the area with 13 monumental towers, questioning both the location of these sites regarding the water supply, the chronology of their construction and their function(s). At the site scale, the excavations at al-Dhabi 2 reveal the organization of the site including the tower, the dwelling settlement and several Umm an-Nar-type tombs. Excavations focused on the tower’s wall and the settlement area, highlighting the architectural development during the Umm an-Nar period. This all-in-one site, installed on a hill, presents a different layout and function than the Salut towers. The multiproxy approach intends to bring new information about the evolution of local societies in the Oman peninsula during the Early Bronze Age.
