Roman Nymphaeum and Church of Santa Maria della Fiora in Manziana

You're standing near Manziana, on the north-western side of Lake Bracciano. It may look quiet and rural, but this is where one of ancient Rome's great waterworks began. Right here, by the Fosso di Fiora, was the richest source of the Aqua Traiana, the aqueduct built by Emperor Trajan.
