Chiesa di San Leonardo

The church of San Bartolomeo is one of the oldest examples of Romanesque art in Campobasso. The church dates back to the middle of the 13th century and has a facade with a horizontal crown, the central part of which is higher than the sides. The pseudo-prothyrum that adorns the portal is the most obvious element of the façade and consists of two blind arcades divided by two columns leaning against the wall.

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.
