Our current knowledge of Roman aqueducts across the Empire is patchy and uneven. Even if the development of “aqueduct studies” (where engineering, archaeology, architecture, hydraulics, and other disciplines converge) in recent years has improved this situation, one of the aspects which has been generally left aside is the chronology of their late antique phases and of their abandonment. In the Iberian peninsula, there is to date, no general overview of the Roman aqueducts, and all the available information is distributed across various publications, which as expected, hardly mention the late phases. This publication tackles this issue by analysing and reassessing the available evidence for the late phases of the Hispanic aqueducts by looking at a wide range of sources of information, many times derived from the recent interest shown by archaeologists and researchers on late antique urbanism.
