Janiculum Mills Excavations:

Roman water-mills on the Janiculum Hill, Rome. "At the invitation of the American Academy in Rome, and with the kind permission of the Soprintendenza Archeologica di Roma, a 5-week excavation season was undertaken in June and July 1998 to investigate the Aqua Traiana and a large Roman water-mill complex in the Academy's parking lot, on the Janiculum Hill in Rom."
