ROMAQ: The Atlas Project of Roman Aqueducts
Roman aqueducts are amongst the most impressive and interesting structures that have survived from the Ancient World. Although aqueduct bridges such as the Pont du Gard are best known, roman aqueducts are complex water supply line systems that are impressive feats of engineering even by today's standards. Some of the aqueducts are simple water channels, but many contain complex structures such as inverted siphons, tunnels, basins and drop shafts while the channels themselves can be up to 240 km in length. Over 1400 roman aqueducts have been described in the Mediterranean basin and the aim of this website is to present the available corpus of literature on the subject in a systematic way. Besides available literature on each aqueduct, we aim to present summarised data on each aqueduct. However, this is a project in development, and it will take time to add new data and publications, and to update content.
