Gaeta Cathedral

Terracina Cathedral was built between the 5th and 6th centuries using what was left of an ancient Roman temple with five naves in the city's forum. The building has undergone various interventions and restorations, including that of the 11th century, that of the 13th century and, above all, the restoration of the 18th century, which reduced the church from five naves to three with the construction of side chapels and the barrel vaulted ceiling in place of the Romanesque farmhouses.

The co-cathedral of Aquino dates back to the 11th century but during the bombing of the city in 1944 the cathedral was seriously and irreparably damaged. Thus, the present building is a post-war construction. The church was the cathedral of the diocese of Aquino until 30 September 1986, when it became the co-cathedral of the diocese of Sora-Cassino-Aquino-Pontecorvo.

The territorial abbey of Monte Cassino was founded by Benedict of Nursia in 529 on the site of an ancient temple dedicated to Apollo. It is the cradle of the Benedictine order. It served as a retreat for sovereigns and pontiffs such as the Frankish prince Carloman, brother of Pepin the Short, the Lombard king Ratchis, and Saint Gregory. Containing immense riches, including a precious library, it is partly placed under the protection of Rome, with a gallery of precious paintings. Throughout the Middle Ages, the abbey was a lively cultural centre thanks to its abbots, libraries, archives, writing and illumination schools, which transcribed and preserved many works of antiquity. The abbey was destroyed during the Second World War and was rebuilt identically from 1948 to 1956.
