Located in the western part of Molise, Isernia, which is a long and narrow city, stretches across the valley with two rivers, the Carpino and the Sordo. Of ancient origin, the city still bears the traces of the wars between the Romans and the Samnites, who were once the inhabitants of the city. In the city centre, the Cathedral is a perfect indicator of the different periods that make up the history of Isernia. Rebuilt several times due to earthquakes, the church has retained the Neoclassical style of its last restoration which dates back to the 19th Century. It has nevertheless preserved the remains of the pagan temple and the medieval cathedral that followed, both of which are visible through bay windows that have been fitted into the floor. A sort of small loggia built in the Early Middle Ages, the Fraterna Fountain on Celestino V Square is also an interesting site to visit.
