The municipality of Monte Romano, like many of the towns in Tuscia, was characterised by the Etruscan and Roman presence.
The village developed around a road (today's Aurelia Bis) and is located within a valley at the foot of the Rotonda, a very special hill with a summit formed by centuries-old oaks.
It was in this grove of oak trees that the first settlement of Monte Romano, the ancient Arx Montis Roman, was born.
The high position gave it a natural defence against attacks and easy control over the surrounding lands.
After the destruction of the Arx Montis Romani, this territory with the Monte Romano estate and the Rocca Respampani, became the property of the Ospedale del Santo Spirito in Sassia, which exploited these lands by imposing a more structured agricultural organisation on them. The peasants who worked these lands first settled in the old dwellings on the hill and later further down the valley, giving rise to the future colony of Monte Romano.
However, it was in the following century, the 18th, that the real development of Monte Romano took place, with the construction of new architectural elements, such as the Prisons and the Clock Tower, the
Mascherone Fountain and much more.
The route then continues to Civitella Cesi, a village (a hamlet of Blera) perched on a small tuff tongue lapped by the Borgonero ditch to the southwest and the Petrella source ditch to the northeast.
