Along the Sinello and Trigno Valleys

The valleys of the two rivers Sinello and Trigno, in the Province of Chieti, separated by a long mountain chain, connect a number of small centers through a natural itinerary from Vasto to Castiglione Messer Marino and further still towards Agnone and Carovilli in the Province of Campobasso.

The Sinello River

The Sinello river, in some ancient authors called Asinello, has its origin from Mount Fraiano, 1412 mt above sea level, near Castiglione Messer Marino, and collects many small and larger streams flowing in a North-Eastern direction in the territories of Roccaspinalveti, Montazzoli and Guilmi, where the valley gets deep and narrow. Then the valley gets larger in the vicinity of Carpineto, and flows through the territories of Gissi, casalanguida, Monteodorisio, Pollutri, Casalbordino and Villalfonsina, to reach the sea near the station of Casalbordino.

The Trigno River

The Trigno, ancient Trinium which Roman historian plinius called "flumen portuoasum", had in antiquity a large basin at its mouth which ould hosm great numbers of ships and boats. The river has its origin from two springs in the territory of Vastogirardi, now province of Isernia, and gets bigger collecting all the smaller rivers of the area: the Carovilli near pescolanciano, the Durone near Civitanova, the Livello and Venino just north of Bagnoli, the Sente south of Salcito and from this point as far as the Adriatic it marks the borderline between Abruzzo and Molise (formerly between Abruzzo Citeriore and the Province of Campobasso), flowing between two chains of mountains. In the territory of Castelguidone the mountains give way to hills and the river gets still bigger through a number of other contributors.

The Itinerary

The best way to explore the area is following the provincial road called Istonia from Vasto towards Cupello and Monteodorisio. After risind some hundred feet, the view is astounding, On the one side, the Sinello valley and views of Monteodorisio and Casalbordino. On the other side the Trigno valley. Before you the Maiella, behind the Adriatic.

After passing Cupello, which, the tradition says, was founded in the 15th century by a colony of Slavs rejected by the people of Monteodorisio, who built huts in the un-inhabited area where now Cupello rises, we reach Monteodorisio, where we can visit a 13th century church dedicated to St Francis, an ancient tower of the Celestine monastery, in contrada di Sant'Anna outside the little town a pre-Roman chapel, which is evidence of the existence of a Frentani centre in the area (whose name has not reached us). The best view is from the hilltop of the medieval castle. The place takes its name from its count Oderisio Caracciolo, who had a countdom of 17 castles. From the castle on clear days you can see south as far as the Gargano promontory in Apulia and the Tremiti islands.
