According to the myth, was annexed to the city by the sixth king of Rome: Servio Tullio . From him take the name the ancient walls Serviane, which was part of Porta Viminalis, erected in defense of the hill; some of remains are still in piazza dei Cinquecento in a small garden to the left of Termini Station.
