Venafro Cathedral, the largest church of the city, is situated at the foot of Parco Oraziano. Dating from the 5th century, it was built under Bishop Constantine in the place where for centuries there was a pagan temple. It is adorned with materials from other monuments of earlier eras (Roman elements, Christian decorations, and Bishop Pietro di Ravenna's bas-relief which is called "March Settecappotti"). The interior has three naves decorated with paintings from the 14th century. The current appearance is due to renovation works dating back to the 1960s and 1970s which have replacing the ancient Baroque style, bringing the back sacred aspects of the Gothic and Medieval eras. At the end of 1600 the "cappellone" was built; a chapel in which to administer the sacraments.
