- On 1 May 1816, during the time of the reform of the Borbon leaders, Valle San Giovanni became a communal capital. Frazioni (suburbs) under the jurisdiction of Valle San Giovanni included Abatemozzo, Iscarelli, Faieto, Casanova, Poggio Rattieri, Borgonovo, Magliano, Poggio Valle and Valle Piola.
Secondary to the "Leggi ed Atti del Regno d'Italia" (Laws and Acts of the Kingdom of Italy) promologated in the year 1868 Valle San Giovanni on 6 December 1868 lost its communal status. It became itself a frazione Montorio al Vomano.
This explains why, in the early 1900's many immigrants from Valle San Giovanni listed their home of record as Montorio al Vomano. In 1929 VSG became a frazione of the communal city of Teramo where it remains today. These events are important in that individuals searching for their ancestors' birth records born before 1929 will need to go to Montorio al Vomano to obtain these documents.
According to the Ninth General Census of the Population, in 1951 Valle San Giovanni had about 790 inhabitants.
The soil in and around Valle San Giovanni contains extensive reserves of Lignite (which burns easily but leaves a great deal of cinders). Lesser quantities of Marcasite are also present.
In 1814 during the first years of the struggle for the unification of Italy (carbonarismo), a 24 year old soldier from Valle San Giovanni, Geremia Nicolina, was sentenced to death by the occupying Napoleanic rulers. He was shot by musket fire.
Valle San Giovanni sits at an elevation of 587 meters (equivalent to 1929 feet). The median elevation for the country is 337 meters.
Many houses in Valle San Giovanni did not have indoor plumbing until the late 1950's and early 1960's. Construction of the first bathrooms posed somewhat of a problem as the houses tended to be rather small and lacked drainage pipes. One rather common yet innovative way of adding a bathroom involved connecting an attached room to the house, preferrably one that could be placed in an overhanging position. In this example, look closely and you will see a large drainage pipe hanging straight down from the bathroom: 
(click to enlarge) According to one local historical source: "In epoca romana nelle immediate vicinanze dell'attuale Valle San Giovanni passava l'Interamnium Vorsus, il tratto cioè della via Cecilia che, proveniente da Amiternum, all'altezza dell'attuale Montorio deviava verso Interamnia e Castrum Novum, raggiungeva Travazzano, Santa Maria di Ponte a Porto e raggiungeva il mare seguendo il corso del fiume Tordino. Proprio a Valle infatti, in località "Cavonetto", nel 1993 fu rinvenuto il Cippo miliario "CXIIII" insieme a un tratto dell'antica strada. ....(e' possibile) camminare a Valle sull'antico percorso dei ROMANI" TRANSLATION: In the times of the empire a Roman road originated in Amiternum near L'Aquila, crossed a pass near the Gran Sasso, and arrived at Montorio al Vomano where it changed course towards Valle San Giovanni along what is now known as Via Cecilia. From here the road arrived at Travazzano, crossed a small bridge where now stands an ancient church known as Santa Maria di Ponte a Porto, and snaked along the Tordino River in the direction of Teramo and the Adriatic Sea. In 1933 a milestone with the inscription " CXIIII" was discovered in Valle San Giovanni in a location known as "Cavonetto". With some effort it is still possible to follow in the path of this Roman antiquity.
