This lecture presents the preliminary excavation results of the Aventinus Minor Project’s from 2021-2024 and contributes to recent reinterpretations of Rome’s defensive, domestic, and religious topography across space and time. AMP unites excavation with the involvement of multigenerational community members, including local elementary and high school students, and residents of the Instituto Santa Margherita convalescent home.

The site is located between the Circus Maximus and the Baths of Caracalla, adjacent to Santa Balbina Church. Limited 1980’s test trenches and archival research indicated that the site could contain a portion of the presumed Servian Wall, Roman houses, early Christian architecture, and Renaissance vineyards. 

Excavations unearthed a complex multi-use neighborhood with intact strata from modern, Renaissance, late antique, and imperial phases of occupation. Features included an early cistern, Neronian mosaic and fresco fragments, later Roman sewage systems, and a late antique lime kiln, and Renaissance vineyards. The material finds reference the prolonged use of an urban space for evolving domestic, industrial, and religious purposes.

Conversely, AMP’s excavations discovered little conclusive evidence of the Servian Walls, suggesting that the long-accepted assumption that the Walls ran over the top of the hill might be reexamined, and the large opus quadrata blocks could belong to another unspecified building, perhaps an aqueduct. 

Marta Barbato is an archaeologist specialising in ancient numismatics and currently serves as Head of the Coin Cabinet at the National Roman Museum in Rome. She completed her PhD in Classics and Ancient History at the University of Warwick, where her doctoral research examined Roman Republican coin finds from urban excavations in Rome and central Italy.

Her research focuses on patterns of monetary circulation, hoard evidence, and the economic and communicative functions of coinage in the late Roman Republic and early Empire. She has published widely in international journals, including The Numismatic Chronicle, Revue Belge de Numismatique et de Sigillographie, and Mélanges de l’École française de Rome. She is also Co-Director of Ancient Numismatics. An International Journal.

Alongside her academic research, she holds a position within the Italian Ministry of Culture, where she contributes to the safeguarding, study, and research of numismatic collections.

This lecture is part of the City of Rome programme, an intensive eight-week residential course directed by Dr. Christopher Siwicki, designed for postgraduates from selected British partner universities. The programme is aimed at students at the Master’s or early Doctoral level studying classical archaeology, art history, ancient history, and the transformation of antiquity in the Middle Ages and modern period.
