Chiesa di San Bartolomeo

The church of San Leonardo was built in the 14th century in Romanesque-Gothic style. In 1338 it was inaugurated and initially run by a religious brotherhood of Dominicans. The earthquake of 1456 damaged the church, which was enlarged inside. The earthquake of 1805 also caused some damage, although not much.

The church of San Giorgio is the oldest church in Campobasso, dating from the 10th century. Elements of pre-existing Romanesque buildings have been incorporated into the outer walls. A pelican on the right side and, at the back, a sun and a donkey's head with a bridle, enrich the simple and elegant structure of the church. The quadrangular bell tower is located at the end of the right side and alternates mullioned and single lancet windows.

The Metropolitan Cathedral of the Holy Trinity was founded in 1504. It was the seat of the Trinity brotherhood, suppressed in 1809, which became famous in the 16th century for its battles with the Crusaders. Destroyed by an earthquake in 1805, the church was rebuilt to a design by the architect Bernardino Musenga. It was reopened for worship in 1829, becoming a parish church and the seat of the collegiate chapter. In 1860, it was closed to worship and used by regular troops as a barracks. In 1900 it was reopened to the faithful and became a cathedral in 1927.
