Narbonne Cathedral,dedicated to Saints Justus and Pastor, was the seat of the Archbishop of Narbonne until the Archbishopric was merged into the Diocese of Carcassonne under the Concordat of 1801. The church was declared a basilica minor in 1886. The building, begun in 1272, is noted for being unfinished.
The site has a long history as a place of worship. In 313, just after the Edict of Milan, a Constantinian basilica was erected on approximately the same spot as the present cathedral. Ruined by a fire in 441, it took 37 days to demolish those parts of the basilica that had escaped destruction. Then a Latin basilica was constructed by Bishop Rusticus, who was encouraged in his work by the Gaulish prefect, Marcellus. The basilica was finished on November 29, 445. Originally dedicated to Saint Genesius of Arles, it was re-dedicated in 782 to the young Spanish martyrs Saint Justus and Pastor. Little remains of this building: two Roman columns from the former forum, used in the nave, can now be seen in the present cloister; the lintel and an aedicule of white marble can now be seen in the Lapidary Museum of Narbonne.
A Carolingian cathedral was erected in 890 by Archbishop Theodard (d. 893). Its steeple, largely restored, is visible from the cloister. Yet despite the help given to it by three popes, this church fell into ruin.
The idea to build a Gothic cathedral was a political decision made in 1268 by Pope Clement IV, the former archbishop of Narbonne. He decided that it would be a monument made in the magnificent style of the Kingdom of France. The construction of the new cathedral was supposed to begin in 1264, but did not actually start until 1272. The first stone of the current cathedral was laid by Archbishop Maruin on April 13, 1272, in the foundation of the current Chapel of the Sacred Heart.
The choir was finished in 1332, but the rest of the building was never completed, as the result of many factors including sudden changes in the economic status of Narbonne, its unusual size and geographical location (to complete it would have meant demolishing the city wall) and financial constraints.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
