On the death of Virginio Vespignani, the work was continued by his son Francesco and by the architect Costantino Sneider, his assistant, as is recorded in a stone by the entrance to the campanile.
[3] The west front of the cathedral is divided into two by a cornice: below are three portals (of which that in the centre has spiral columns and capitals) and above, between two oculi, a Romanesque rose window, an artistic glory of the city.
The campanile of 1914 is a recent construction, occasioned by the demolition of the preceding one, which was dangerous because of damage caused by an earthquake at the end of the 18th century.
Of artistic note is the high altar, rebuilt on site in 1965 using 14th-century elements of the original: of especial value are the bas reliefs by Guglielmo Ciani of Perugia depicting episodes from the life of Saint Benedict of Nursia.
One of the side chapels is dedicated to one of the patron saints of the city, the hermit Blessed Angelo,[4] whose remains rest in an urn of bronze and silver.
