Vaulted funerary hypogea are familial collective tombs containing multiple progressive burials. This funerary type, only sporadically attested in Mesopotamia in the third millennium BC, spread rapidly from the beginning of the second millennium BC and is attested throughout the first millennium BC across a vast geographical area: in the Middle Euphrates region, in Mesopotamia and in Khuzestan. These hypogea are characterized by specific architectural features and localizations, which we will analyse in this work. In fact, they have a complex structure that required specific technical knowledge, especially for the realization of the vault roofing: corbelled vault, with radial arrangement or with tilted rows. Moreover, they were generally located under domestic dwellings or, to a rare extent, under palaces. Analysing the excavation reports which describe these tombs, it is clear that this relationship is a recurring element. This indicates the strong connection between the living and the dead, which is also suggested by the use of similar plans, both in graves and in houses.
