Recent archaeological discoveries have confirmed the Etruscan origins (4th-3rd centuries BC) of Celleno Vecchio, a settlement that enjoyed a great position, i.e. the ancient communication route between Orvieto, Bagnoregio and Ferento.
Ancient sources provide evidence that this medieval settlement is one of the fortified villages built by the Counts of Bagnoregio between the 10th and 11th centuries. At that time, the village must have consisted of a number of dwellings at the end of the tuff, protected by cliffs on three sides, surrounded by walls and a small fortress, which is now the Orsini Castle, to protect the only access route.
At the end of the 12th century, after the destruction of Ferento, the municipality of Viterbo began a rapid expansion in the Tiber Valley, also acquiring Celleno, which in 1237 was one of the castles of the Viterbo area governed by a Podest (high official) appointed by the local government. At the end of the 14th century, the city center fell into the hands of the Gatti family, one of the most powerful families in Viterbo. During this period, the medieval fortress was completely renovated and converted into a fortified stately home that can still be seen today. The Gatti family ruled Celleno until the last heir, Giovanni Gatti, who was killed on the orders of Pope Alexander VI (Borgia) for refusing to return the castle. At the beginning of the 16th century, the municipality fell into the hands of the Orsini family. Interestingly, the castle still bears the name of this family. Only towards the end of the 16th century was the church able to incorporate Celleno into its possessions until the unification of Italy.
In modern times, Celleno Vecchio was often affected by earthquakes and landslides, until it was finally abandoned in the 1930s.
Today it is a small, charming and evocative ghost village, characterized by ruins and vegetation, with beautiful views of the surrounding landscape.
