Church of San Pietro

On the medieval cardo outside the city there is a lookout transformed into a public park. Next door is the church of San Marco Evangelista. The original Romanesque construction dates back to the 11th century and is connected to the re-foundation of the town which took place under the rule of the Borrello family, linked to the Republic of Venice. The original building was in fact built by Venetians called by Landolfo Borrello. The lack of a semicircular apse and the presence of the bell tower on the bare façade suggest an inversion in the direction of the main axis during construction. The plan is irregular and the nave is single and has no transept, while there are side chapels. A series of contributions from subsequent periods are evident: Venetian Gothic arches precede the main altar, while the portal is Renaissance and the ceiling is polychrome coffered, in Venetian Baroque style. The wooden altars are also Baroque, while other furnishings range from various eras. For example, a valuable statue of the Madonna and Child is from the 13th-14th century while a statue of Saint Nicholas is by the eighteenth-century sculptor Giovannitti. The building was restored by the regional superintendence of fine arts.

The small but precious Church of San Giacomo Apostolo, also called the SS. Trinità was built in the 13th century but its bell tower dates back to 1895. It is located in Piazza Plebiscito, where the main road routes of Agnone converge. The Governor's Palace (formerly the Magistrate's Court) and the Palazzo dei Conti Martisciano (later Bonanni) also overlook the same square, facing each other, with a splendid Catalan portal.

The church of San Francesco is considered a national monument. Dating back to the 14th century, it has a characteristic Gothic portal surmounted by a fascinating rose window. Worth highlighting is the superb drum dome and the original bell tower (with the final part in wrought iron). Inside the church, with decorations by Ambrosio Piazza, there are very rich altars and frescoes by Paolo Gamba from Molise. Adjacent to the church of San Francesco is the former convent of the Conventual Fathers, with a cloister (on whose walls there are frescoes representing the life of San Francesco), home to the municipal library and the permanent exhibition of ancient books with very rare volumes, including including an ancient copy of Plato's Opera Omnia, dating back to the 16th century.

Agnone is famous throughout Italy and Europe for the presence of the ancient Marinelli Foundry, which is in perfect working order and in full swing. Its origins date back to the Middle Ages, and the foundry is remembered for the manufacture of bells for high-profile buildings such as the Cathedral of the Blessed Virgin of the Holy Rosary of Pompeii and the Abbey of Montecassino. The first official bells cast by the Marinelli foundry date back to 1339, by the director Nicodemo Marinelli, known as "Campanarus". In the following two centuries, when Italy passed into the hands of the Aragonese, the Marinellis continued to cast bells for the various churches and bell towers that were built throughout the peninsula. In 1924 Pope Pius At the beginning of the 20th century, the Marinellis were called by many churches throughout Italy because the systems for swinging the bells were now obsolete or seriously damaged. When in 1944 the Nazi German occupiers, who had been in civil war with Italy for a year, also arrived in Abruzzo and Molise, the foundry was closed and used as headquarters for battle missions. Furthermore, the bells that were being melted at that time were destroyed by the Nazis and remelted to create combat cannons. Once the Germans were defeated by the Americans, in 1949 the Marinelli foundry remained famous for its contribution, and its name was still on everyone's lips: a reference point for the casting of new bells. After the Second World War in Italy, the Marinellis built the concert of bells for the cathedral of Montecassino, destroyed during the famous battle of the Second World War, and so they continue to contribute to this day, whenever a new church is built, casting the bells necessary for new concerts.
