In order to reconstruct the geology and the original morphology of the Capitoline Hill, nowadays hindered by the secular presence of
human settlements and by a thick cover of manmade fill, we have combined the study of the remaining outcrops with the re-interpretation of 104 borehole stratigraphies. By using a modern concept to describe the stratigraphy of the area of Rome, which is based on the definition of aggradational successions deposited in response to sea-level rise at each glacial termination, and using radiometric ages determined on interbedded volcanic products of the Colli Albani and Monti Sabatini districts, we have been able to reconstruct stratigraphic relationships among different sedimentary cycles and to reinterpret some ancient geologic sections known in the literature.
We also have made a detailed hydrogeologic study of the Hill, which allowed us to identify the alimentation of the Tullianum spring and to recognize a new spring: the Fons Servilli. Finally, we present here a diachronic picture of the hydric supply of the Capitoline Hill.
