About Isernia Cathedral

Isernia Cathedral is the principal Roman Catholic cathedral in the city of Isernia, in the Molise region of southern Italy. It functions as the seat of the Diocese of Isernia-Venafro and combines medieval and later architectural elements.

The cathedral’s fabric reflects multiple construction phases and restorations, typical of cathedrals in this seismic region, with visible medieval masonry alongside later renovations. Interior spaces include the main nave and chapels that reflect successive stylistic periods.

Historically the cathedral occupies the site of an early medieval episcopal church and has been rebuilt or repaired several times following earthquake damage and later refurbishments. It remains an active parish and diocesan church with liturgical and civic functions.

The cathedral sits in Isernia’s historic center in Molise, close to the town’s main civic and archaeological sites and easily reached from local streets and public squares.

  • Diocesan seat: The building serves as the cathedral church for the Roman Catholic Diocese of Isernia-Venafro and sits in the historic center of Isernia.
