Cathedral of Voghera, Renaissance cathedral in Voghera, Italy

The Cathedral of Voghera is a Renaissance-style religious building featuring balanced proportions, classical elements, and columns arranged across its broad facade. The structure serves as the main church within the Roman Catholic Diocese of Tortona and occupies a central role in the city's religious life.

Rebuilt from 1605 to a design by Antonio Maria Corbetta, who took the Bramante plan of Pavia Cathedral as his model. The facade stayed unfinished for lack of funds until Carlo Maciachini added a final bay and completed it between 1874 and 1881, flanking the main entrance with the chapels of Maria Bambina and the baptistery.

The cathedral keeps a reliquary holding a fragment of the Holy Thorn, said to have arrived with crusaders returning from the Holy Land and kept in Voghera for about 700 years. On the feast of Saint Bovo it was shown to the people by the bishop, and thousands knelt for the blessing. Medieval antiphonaries donated by the Visconti family survive, though many initials were stolen during the Second World War.

The cathedral is entered from via Cavour, not from a square. The unfinished facade long delayed the main entrance, and the 1874–1881 Maciachini work added the final bay and the two lateral chapels flanking the portal: Maria Bambina and the Immacolata on the right, the baptistery on the left. Look up at the octagonal tiburio, the most recognisable element of Voghera's skyline.

The cathedral keeps medieval antiphonaries whose illuminated initials are attributed to the Master of the Vitae Imperatorum, active in the 1430s, and were donated by the Visconti family of Milan. Many initials were stolen during the Second World War, probably by a German officer after the gold grounds.
