Also called “Regina Viarum”, it was opened in 312 BC by censor Appio Claudio Cieco, who modified the ancient route that connected Rome to the Alban Hills, leading to Capua and passing through the towns of Ariccia, Terracina, Fondi and Formia. Around the year 190 BC it was extended up to Brindisi. Very much used in the Middle Ages, it fell then into disuse and was reopened by Pope Pius VI at the end of the 18 th century. In 1931 “the creation of a very large park” was planned, but it was only in 1962 that part of its soil was turned into a public park and in 1976 the area of the Caffarella was expropriated and added to it. Though victim of many forms of degradation, the beauty and charm of this road reside in the fact that it still is one of the few surviving evidences of the Roman Countryside, with its several ruins.
