The cathedral replaced a 12th-century structure that was allegedly destroyed on orders of Napoleon Bonaparte during his occupation of Italy.
The interior contains a 19th-century pipe organ that remains a focal point for the cathedral's liturgical music programs.
The cathedral is part of a complex that includes the Bishop's Palace, which holds historical archives spanning several centuries of local ecclesiastical history.
The architectural style is strictly Neoclassical, designed to project a sense of order and structural clarity typical of the early Napoleonic architectural influence in the Piedmont region.
The Alessandria Cathedral, dedicated to Saint Peter the Apostle, stands as the principal place of worship in the city and serves as the seat of the Bishop of Alessandria. The current Neoclassical building was constructed between 1807 and 1810 on the site of a much older medieval cathedral that was demolished during the Napoleonic era. Its facade is characterized by a prominent portico supported by massive columns, reflecting the architectural transition of the early 19th century. Inside, the church features a Latin cross plan with three naves divided by substantial pillars. It houses significant religious art, including several notable altarpieces and wood-carved elements that survived the transition from the previous structures. The cathedral complex is integral to the historic urban layout of the central Piazza Giovanni XXIII.

Visit during the early morning on weekdays to experience the space during quiet periods before local services.
Look for the smaller, historical architectural fragments preserved in the side chapels that date back to the pre-Napoleonic era.
Check the diocesan website periodically for information on liturgical concerts held inside the main nave.
Avoid visiting during Sunday morning services if you intend to tour the architecture, as tourists may be restricted to the back of the nave.
Shoulders and knees must be covered; maintain a quiet tone and refrain from photography during active services.
