The Comino Valley: a guide to Lazio's hidden gem of nature, villages and history
La Comino Valley is a basin nestled between the rugged chain of the’Central Apennines and the group of Mount Cairo, in the extreme south-eastern corner of Lazio, on the border with the’Abruzzo and the Molise.
It is a secluded valley, but at the same time close to the great channel of communication, represented by the Autostrada del Sole motorway and the railway, which connects northern and southern Italy.
It is crossed by the expressway that connects Cassino a Sora, from where it appears as a large natural amphitheatre some fifteen kilometres wide and some twenty kilometres long, with the mountains acting as a rampart and the villages, arranged in a lodge-like half-castle, dominating a landscape of rolling hills covered with vines and olive trees.
Opposite have other villages clinging to the spurs, where forests of oak, hornbeam and chestnut trees and, at higher altitudes, conifers and beech trees, alternate with bare ridges or barely spotted with sparse shrubs.
Includes the territory of 11 Municipalities of the Upper Melfa basin area (Atina, Villa Latina, S. Biagio Saracinisco, Picinisco, Settefrati, S. Donato Val di Comino, Gallinaro, Alvito, Vicalvi, Casalvieri and Casalattico).
At XIV Mountain Community, called “della Valle di Comino”, nine other neighbouring municipalities belong to the basin of the Medio-Liri, to the north (Campoli Appennino, Pescosolido, Posta Fibreno and Fontechiari) and of the Rapido, to the south (Belmonte Castello, Acquafondata, Vallerotonda and Viticuso), with a total of 22,000 inhabitants spread over a total area of about 300 square kilometres (slightly more than the Island of Elba).
The largest municipality is Atina with 4,258 inhabitants. They are followed by Casalvieri, with 2,679, Alvito, with 2,614 and S. Donato Val di Comino with 2,076. All others are between two thousand and three hundred inhabitants.
A mysterious valley
It is a land where history is intertwined with mysteries, myths and legends. Even its name is shrouded in mystery.
In the opinion of many, it derives from Cominio, the city destroyed in the year 293 B.C. together with Aquilonia, in the last desperate and bloody battle fought by the Samnites against the growing power of Rome, as narrated by Titus Livius and by Dionysius of Halicarnassus.
Others derive it from the Comini, one of the four peoples of the Equicoli, also proud adversaries of the Romans and defeated by them or by “cominia”, a quality of olive, both taken from Pliny the Elder's monumental work.
The toponym, which had disappeared for more than seven centuries, reappears in an act from the archives of the Benedictine Abbey of S. Vincenzo al Volturno dating back to 778 A.D., by which the Duke of Spoleto, Ildebrando, donated to it the churches of S. Donato and S. Giuliano, located “in Cumin territory”.
In later documents, the name Cominio indicates a territory or a county, sometimes restricted and sometimes enlarged to include even Atina, but whose core was the area between Vicalvi, Alvito, Gallinaro, S. Donato V.C. and Settefrati.

Flavio Biondo
In the mid-15th century, Flavio Biondo in his work, writes of “It is surrounded by very high mountains and has eight well-populated castles, Vicaglio, Alvito, S. Donato, Sette frati, Picinisco, Gallinaro and Casalviero: this district was called Cominio by the ancients, from a city that was so called, of which the people of the area do not know where it was, and of which Livy makes mention. In that same district on the right hand under the mountains is Atina, a very ancient city, on the side of which flows the river Melfa, which has its source in the Apennines, and goes to mix with the Garigliano near Pontecorvo: Vergilius mentions this city, and Livy himself”.

A century later, also one of the most important geographers of the time, Leandro Alberti writes about “a pleasant and fertile region”, comprising “eight castles”, and, like Biondo, accorded a certain distinction to Atina, located in the western part of the same area.
In the next two centuries (17th and 18th), during the domination of the Gallio family, the terms Duchy of Alvito and Cominese coincided, at least in popular vernacular and literature, although Casalvieri and Casalattico did not belong to that political unit, while it included Belmonte Castello, located immediately outside the valley basin.
The 19th Century
At the beginning of the 19th century, it first appeared as the toponym of a “valley” whose scope was limited to the villages on the north-eastern side and, in 1862, the municipality of S. Donato, in order to distinguish itself from others with the same name, obtained from King Victor Emmanuel II the right to add the attribute of “Val di Comino”.”.
Even in the early 1900s, according to a local historian, for Comino Valley meant only the north-eastern area, i.e. the area between Settefrati, S. Donato (with Gallinaro, then its hamlet), Alvito and Vicalvi.
Not even the generous attempt of a great geographer, Roberto Almagià, helped to give it a name. Therefore, even today, its name does not appear on official maps. So officially it does not exist, but in fact it does.
