Appunti di topografia per la storia di Numana

An examination of archival documents, starting with L. Spada's notes, in the Biblioteca Comunale in Osimo, and, even more so, the analysis and plotting of the preserved Roman monuments provide valuable information about a generally neglected phase of the city of Numana.
In addition to the few remains in opus reticulatum and opus caementicium, visible in the north-east sector of the modern town, of particular importance is the subterranean aqueduct, in use until a few decades ago, which crossed Numana from Capo d'Acqua, south-west of Sirolo, to the port.
