The Romanesque cathedral was built between 1132 and 1166 by bishop Roberto of Avellino , who dedicated it to Saint Modestinus . It kept its original appearance until the end of the 17th century , when a series of refurbishments and renovations began which , continuing into the 18th century , eventually transformed the building into a Baroque one . Bishop Francesco Gallo ( 1855 – 1896 ) gave the cathedral a further overhaul , creating its present Neoclassical appearance . The refacing of the west front was entrusted to the architect Pasquale Cardola and was completed between 1857 and 1868 , while the conversion of the interior was the work of the architect Vincenzo Varriale between 1880 and 1889 . The new building was subjected to the bombing of World War II and the 1980 Irpinia earthquake , both of which made necessary further significant stabilisation and reinforcement of the structure
