Abstract The Nabataean monumental rock‐cut tombs in the oasis of al‐Badʿ are the main heritage and tourist attraction of the Madyan peninsula, in the heart of the Neom region in Saudi Arabia. Through an analysis of their architectural and decorative features, this study provides, for the first time, a thorough overview of the 35 tombs in the necropolises of Mughāyir Shuʿayb and al‐Aṣīfir. A multiscalar examination sheds light on the processes used in their realisation, assesses the investments required for their execution and the status of the sponsors, and thus reveals a social and spatial ranking of the Nabataean necropolis. The study also reveals a ‘cultural’ standardisation of the tombs in terms of the techniques used to cut and decorate them, as well as a local particularity dependent on topography, geomorphology, culture and personal choices. The presence of these impressive funerary monuments at al‐Badʿ confirms the siteʼs major economic, political and cultural role within the Nabataean world, as well as the importance of the caravan route leading from the Red Sea ports to the major urban centres of the southern Levant, including Petra.
