The Aqua Augusta, built between 33 and 12 B.C., supplied at least eight cities across the Bay of Naples via a 90-mile gravity-fed system sourced from springs at Serino.
Beneath Todi's Piazza del Popolo lie 30 cisterns and over 500 wells spanning pre-Roman, Roman, and medieval periods, with a combined storage capacity of 30,000 cubic metres.
From Perugia's Etruscan well (3rd century B.C.) to Orvieto's Pozzo della Cava, which joined the UNESCO-IHP Global Network of Water Museums in 2023, Italian wells are documented across a wide range of conservation states.
The Aqua Augusta — later redocumented after a 647-metre section was rediscovered beneath Posillipo Hill in 2022 — remains the most complex multi-city aqueduct known from antiquity. Channels carved into tufa limestone carried water from Serino springs some 51 kilometres east of Naples, distributing it to Pompeii, Herculaneum, Cumae, and five additional settlements through ten distinct branch lines.
Key Findings
What the underground record shows
The Aqua Augusta branched into seven urban lines and three supplying wealthy villas — an arrangement documented by no other Roman aqueduct of the same period.
The twin cistern complexes beneath Todi's Piazza del Popolo held a combined 30,000 cubic metres of water, constructed in opus caementicium with barrel-vault ceilings eight metres high.
The Santu Antine di Genoni well in Sardinia, at 39.85 metres, is currently the deepest Nuragic well documented. Its upper section uses precisely moulded trachyte ashlars, transitioning to limestone below.
Documentary evidence from Todi shows that medieval cistern construction began integrating with the Roman system as early as 1262, when the eastern complex beneath the Palazzo dei Priori was first recorded. The pattern held across hill towns of Umbria and Lazio, where hilltop geology forced both Roman engineers and medieval builders toward similar technical solutions: gravity collection from roof surfaces and spring capture through tufa channels.
Archive Context
About this archive
Maplewell documents the physical and documentary record of water infrastructure in Italian historic towns. Coverage focuses on the period from the late Roman Republic through the end of the medieval era, with attention to current conservation and access conditions.
Content draws from site visits, archaeological reports from Italian regional authorities, and peer-reviewed hydroarchaeological literature. Where direct measurements or administrative classifications are cited, sources are identified in each article.
