 Monterubiaglio has approximately 600 inhabitants, but during the summer time the population grows much larger as it is a popular vacation spot for persons who are originally from the village but may have moved elsewhere such as Rome.Since 2006, the Department of Classics at Saint Anselm College has been excavating an Etrusco-Romano site just below Monterubiaglio.The excavation has yielded a number of finds and structures that date from the 8th century BCE to the 10th CE.
