Ancient origins

The basilica is built upon a Christian necropolis dating to the 4th century. The epitaph of Flavinus was engraved beneath a representation of a chrism on the lid of a sarcophagus dating to between 365 and 385, testifying to the Christian presence in Bordeaux to Late Antiquity. This epitaph was extracted during an excavation of the necropolis in 1909. Today, it is housed in the Museum of Aquitaine in Bordeaux.^[2]

Foundation legends

Named after the fourth bishop and patron saint of Bordeaux, the history of the basilica begins with the founding of the Abbey of Saint Severinus in the 4th century.

Saint Severinus, born in the Levant, arrived in Bordeaux in the 4th century and met Bishop Amandus. Gregory of Tours tells the story in his work In Gloria Confessorum: "the Bishop Amandus who governs the church of Bordeaux has a dream one night in which the Lord says to him, 'Lift up and go meet my servant Severin...', and now Saint Severin was coming to meet him. Approaching one another, they greeted each other by name, threw themselves in each other's arms, prayed, kissed and entered the church singing psalms". Thus Severinus became bishop of Bordeaux.

Another legend involving the basilica is that of the Oliphant of Roland (nephew to Charlemagne and famous for his death at Roncevaux) being placed on the altar by the emperor while carrying the remains of the valiant knight. The famous Song of Roland recounts this: "Vint a Burdeles, la citet de... Desur l’alter seint Sevrin le baron Met l’oliphan plein d’or e de manguns: Li pelerin le veient ki la vunt".^[3] A Great Step in the Way of Compostela in the Middle Ages, the pilgrims are invited to pass by Saint Severinus to contemplate this relic.

Mid-5th century

Despite the legends surrounding the founding of the church, the presence of an early religious building is attested to in the mid 5th century. It was probably a temple or an oratory. It disappeared in the 9th century due to Viking invasions.

11th–13th centuries

At the beginning of the 11th century, the canons of the basilica decided to commence a major reconstruction. It has the shape of a robust Romanesque church in the basilical form. Frequented by pilgrims on the Ways of Saint James of Compostela, the canons led the travelers up to the choir and down into the crypt so that they could see them. During this period, the basilica was the scene of an investiture ceremony consecrating access to power over the County of Bordeaux, especially by the Dukes of Aquitaine.^[4]

During the course of the 11th through 13th centuries the nave and the choir were built. In the 13th century, the canons ordered the construction of the southern entry which is surmounted by a porch with a belfry built in the Renaissance style. They also built a monumental Gothic entrance for the necropolis. The entrance consists of a large bay flanked by two blind arches and is decorated with fourteen carved statues representing the twelve apostles and two female statues representing the Synagogue and the Church. The church has three tympana: the main one is decorated with scenes from the Resurrection and the Judgement; the left has a representation of the holy women who visited the tomb; and the right depicts the arrival of Saint Severinus according to Saint Amand's dream. The five-sided porch that leads to it was built later.

14th–18th centuries

The 14th and 15th centuries mark the construction of several chapels. One of them was the Chapel of Madonna of the Rose which was dedicated to the Virgin. It contains an altar that was consecrated by Archbishop Pey Berland in 1444. It was designed in the flamboyant Gothic architecture reminiscent of that found in late-15th-century Normandy and England.

Twice in 1566 and 1698, parts of the church's vault structure collapsed causing serious damage. At the beginning of the 18th century, the architect Jean-Baptiste Augier was charged with rebuilding and bracing them with pillars equipped with stone belt courses. During this repair, he ordered that the floor be backfilled because of its considerable unevenness (nearly three meters). These repairs led to the burial of the crypt and a major modification of the ground of the western porch which dated to the 11th century.

19th century

Though the Basilica of Saint Severinus was spared during the French Revolution, it was headed for a century of profound changes in the 1800s.

In the late 1820s, the western façade was restored by order of the Saint Severinus Building Council. To accomplish this the council hired architect Pierre-Alexandre Poitevin to create a neo-Romanesque façade. The construction of the porch gate hides the Romanesque porch.

Sculptor Dominique Fortuné Maggesi (1801-1892), an artist from Carrara who would go one to the greatest sculptor in the history of Bordeaux, was chosen to decorate the façade. He adorned the entrance with statues of Saint Severinus and Saint Amand whose encounter is depicted on the tympanum.He also carved statues of Saint John and Saint Peter which adorn the balustrade on the upper floor. This was done to give homogeneity to both the façade and Romanesque bell tower of the basilica.^[6]

In 1840, the Basilica of Saint Severinus was listed in the Inventory of Historic Monuments (French: l'inventaire des Monuments Historiques). Following this classification, its choir was completely reorganized and a new marble altar was made.. Arcades were opened and two chapels were dedicated: one to Saint Fort and other one to the Sacred Heart. They were built on the north side of the basilica. The painter and glassmaker Joseph Villiet signed the stained glass windows of the nave that he created which depict scenes from the bible as well as the history and legends that surround the basilica.

20th century

After it was classified as an historic monument on the List of 1840, it was then inscribed as a UNESCO World Heritage Site in 1998 due to it being the head of one of the Ways of Saint James of Compostela.

Church crypt

The original crypt was located in a 5th-century building. Its later use as a funerary basilica is attested to by the presence of sarcophagi which supposedly contained the remains of early bishops.

In 1635, the Carolingian apse in the basilica was removed to allow for the creation three recesses for the sarcophagi and the cenotaph of Saint Fort. At the time, this martyr was the object of a cult that lasted until recently. In fact, every May 16^[7] mothers led their sons to the grave of Saint Fort to get "fortified".

Archaeological crypt

The archaeological crypt is a vestige of early Christian cemetery and is one of the oldest in Bordeaux. It was situated between Place des Martyrs de la Resistance and Rue Judaïque. According to tradition, the necropolis at Saint Severinus was consecrated by Christ and seven bishops. The tradition also states that many of the rulers of Roncevaux are buried there. This would explain why this place was a magnet for pilgrims in the Middle Ages.

From 1909 to 1910 excavations were conducted south of the church by Paul Courteault. In part of the necropolis superimposed graves were discovered that dated from the 4th to 13th centuries. In the late 1950s and then from 1964 to 1969, Raymond Duru campaigned to get the crypt open to the public. Thanks to his efforts, it has been publicly accessible since the 1980s.
