Ager Romanus

It is limited to the south by the Monti Prenestini range, Alban Hills and Pontine Marshes; to the west by the Tyrrhenian Sea; to the north by the hills surrounding Lake Bracciano and to the east by the Monti Tiburtini range.

[1] The Rome of Romulus and his immediate successors possessed a very restricted territory, as did neighbouring Latin cities such as Praeneste.

According to tradition, Rome rapidly outgrew the ager established by its founder, and rather than accept its confinement, Tullus Hostilius razed the Latin city of Alba Longa ca.

The Ager Romanus, as a political zone subject to the municipium of Rome, theoretically continued to extend ad centesimum lapidem, but in practice many of its regions ended up in Lombard hands, with still others managed by the religious authorities or the pope, who were beginning to manage their territories by means of patrimonia and domuscultae.

The confines of the Comunità di Roma were thus finally defined and no longer nebulous, and these limits ended at the constitution of the commune of Pomezia (also including present-day Ardea) following its lasting foundation during the "bonifica fascista" and – in the 1990s – of Fiumicino.
