The Colfiorito plateau, on the border between Umbria and Marche, was located halfway, between the post office of Casenove di Foligno and that of Serravalle del Chienti, which owed its name to the "narrowing of the valley between two very high mountains". Indeed, up to the next station of Pontelatrave, and further on to Tolentino, the orography of the valley did not allow alternatives to the route, forcing it to follow the course of the river. Today "traced" by the State Road 77, it passed by the convent of San Bartolomeo on Mount Brogliano, which in the 14th century saw the reform of the Observants and where in 1814 Pius VII, returning from Loreto, was greeted by the bishop of Nocera Francesco Piervissani. Then it turned east, the Varano fortress, to reach the church of Santa Lucia in the village of Serravalle, finally continuing towards Bavareto and Muccia.
