The Basilica of Saint-Denis (French: basilique royale Saint-Denis; now formally known as the basilique cathédrale Saint-Denis) is a Roman Catholic cathedral that originated as a medieval abbey church. It is located in the commune of Saint-Denis, a northern suburb of Paris, France. The building is of singular importance historically and architecturally because its choir, completed in 1144, is widely considered the first structure to employ all of the elements of Gothic architecture.
The basilica became a place of pilgrimage and a necropolis containing the tombs of the kings of France, including nearly every king from the 10th century to Louis XVIII in the 19th century. Henry IV of France came to Saint-Denis to renounce his Protestant faith formally and become a Catholic. The queens of France were crowned at Saint-Denis, and the regalia, including the sword used for crowning the kings and the royal sceptre, were kept at Saint-Denis between coronations.
The site originated as a Gallo-Roman cemetery in late Roman times. The archaeological remains still lie beneath the cathedral; the graves indicate a mixture of Christian and pre-Christian burial practices. Around the year 475, Saint Genevieve purchased some land and built Saint-Denys de la Chapelle. In 636, on the orders of Dagobert I, the relics of Denis of Paris, a patron saint of France, were reinterred in the basilica. The relics of Saint Denis, which had been transferred to the parish church of the town in 1795, were brought back again to the abbey in 1819.
During the 12th century, the abbot Suger rebuilt portions of the abbey church using innovative structural and decorative features. In doing so, he is said to have created the first truly Gothic building. In the following century, the master-builder Pierre de Montreuil rebuilt the nave and the transepts in the new Rayonnant Gothic style.
The abbey church became a cathedral upon the formation of the Diocese of Saint-Denis in 1966, and it is the seat of the Bishop of Saint-Denis, currently (since 2024) Étienne Guillet. Although known as the "Basilica of Saint-Denis", the cathedral has not been granted the title of Minor Basilica by the Holy See.
The 86-metre-tall (282-foot) spire, dismantled in the 19th century, is to be rebuilt. The project, initiated more than 30 years ago, was decided in 2018 with a signed agreement, with initial restoration work beginning in 2022. Since 2025, reconstruction work has been underway, allowing visitors to the cathedral to observe the building works as part of their tour. The project is planned to be completed by 2029, with a cost of 37 million euros.
History
Early churches
The cathedral is situated on the site where Saint Denis, the first bishop of Paris, is believed to have been buried. According to the "Life of Saint Genevieve", written in about 520, he was sent by Pope Clement I to evangelise the Parisii, but was arrested and condemned by the Roman authorities. Along with two of his followers, the priest Rusticus and deacon Eleutherus, he was decapitated on the hill of Montmartre in about 250. According to the legend, he is said to have carried his head four leagues to the Roman settlement of Catulliacus, the site of the current church, and indicated that it was where he wanted to be buried. A martyrium was erected on the site of his grave in about 313, and was enlarged into a basilica with the addition of tombs and monuments under Saint Genevieve. These included a royal tomb, that of Aregonde, the wife of King Clothar I.
Dagobert I, King of the Franks (reigned 628 to 637), transformed the church into the Abbey of Saint Denis, a Benedictine monastery in 632. It soon grew to a community of more than five hundred monks, plus their servants.Dagobert also commissioned a new shrine to house the saint's remains, which was created by his chief councillor, Eligius, a goldsmith by training. An early vita of Saint Eligius describes the shrine:
:Above all, Eligius fabricated a mausoleum for the holy martyr Denis in the city of Paris with a wonderful marble ciborium over it marvelously decorated with gold and gems. He composed a crest [at the top of a tomb] and a magnificent frontal and surrounded the throne of the altar with golden axes in a circle. He placed golden apples there, round and jeweled. He made a pulpit and a gate of silver and a roof for the throne of the altar on silver axes. He made a covering in the place before the tomb and fabricated an outside altar at the feet of the holy martyr. So much industry did he lavish there, at the king's request, and poured out so much that scarcely a single ornament was left in Gaul, and it is the greatest wonder of all to this very day.
The Carolingian church
During his second coronation at Saint-Denis after Soissons, King Pepin the Short made a vow to rebuild the old abbey. The first church mentioned in the chronicles was begun in 754 and completed under Charlemagne, who was present at its consecration in 775. By 832, the abbey had been granted a remunerative whaling concession on the Cotentin Peninsula.
According to one of the abbey's many foundation myths a leper, who was sleeping in the nearly completed church the night before its planned consecration, witnessed a blaze of light from which Christ, accompanied by St. Denis and a host of angels, emerged to conduct the consecration ceremony himself. Before leaving, Christ healed the leper, tearing off his diseased skin to reveal a perfect complexion underneath. A mis-shapen patch on a marble column was said to be the leper's former skin, which stuck there when Christ discarded it. Having been consecrated by Christ, the fabric of the building was itself regarded as sacred.
Most of what is now known about the Carolingian church at Saint-Denis resulted from a lengthy series of excavations begun under the American art historian Sumner McKnight Crosby in 1937. The structure altogether was about eighty meters long, with an imposing facade, a nave divided into three sections by two rows of marble columns, a transept, and apse and at the east end. During important religious celebrations, the interior of the church was lit with 1250 lamps. Beneath the apse, in imitation of St. Peter's in Rome, a crypt was constructed, with a Confession, or martyr's chapel, in the center. Inside this was a platform on which the sarcophagus of Denis was displayed, with those of his companions Rusticus and Eleutherus on either side. Around the platform was a corridor where pilgrims could circulate, and bays with windows. Traces of painted decoration of this original crypt can be seen in some of the bays.
The crypt was not large enough for the growing number of pilgrims who came, so in about 832 the abbot Hilduin built a second crypt, to the west of the first, and a small new chapel dedicated to the Virgin Mary was constructed next to the apse. The new crypt was extensively rebuilt under Suger in the 12th century.
Suger and the Early Gothic Church (12th century)
Abbot Suger (c. 1081 – 1151), the patron of the rebuilding of the abbey church, had begun his career in the church at the age of ten, and rose to become the abbot in 1122. He was a school companion and then confidant and minister of Louis VI and then of his son Louis VII, and was a regent of Louis VII when the king was absent on the Crusades. He was an accomplished fundraiser, acquiring treasures for the cathedral and collecting an enormous sum for its rebuilding. In about 1135 he began reconstructing and enlarging the abbey. In his account of the work undertaken, Suger explained his decision to rebuild the church was due to the decrepit state of the old structure and its inability to cope with the crowds of pilgrims visiting the shrine of St. Denis.
In the 12th century, thanks largely to Suger, the Basilica became a principal sanctuary of French Royalty, rivalling Reims Cathedral where other French kings were crowned. The abbey also kept the coronation regalia, including the robes, crowns and sceptre. Beginning in 1124, and until the mid-15th century, the kings departed for war carrying the oriflamme, or battle flag, of St. Denis, to give the king the protection of the Saint. It was taken to the abbey only when France was in danger. The flag was retired in 1488, when the Parisians opened the gates of Paris to invading English and Burgundian armies.
First Phase: the west front (1135–1140)
Suger began his rebuilding project at the western end of St. Denis, demolishing the old Carolingian façade with its single, centrally located door. He extended the old nave westwards by an additional four bays and added a massive western narthex, incorporating a new façade and three chapels on the first floor level. In the new design, massive vertical buttresses separated the three doorways and horizontal string-courses and window arcades clearly marked out the divisions. This clear delineation of parts was to influence subsequent west façade designs as a common theme in the development of Gothic architecture and a marked departure from the Romanesque. The portals themselves were sealed by gilded bronze doors, ornamented with scenes from Christ's Passion. They clearly recorded Suger's patronage with the following inscription:
On the lintel below the great tympanum showing the Last Judgement, beneath a carved figure of the kneeling Abbot, was inscribed the more modest plea;
Receive, stern Judge, the prayers of your Suger, Let me be mercifully numbered among your sheep.
Second Phase: the new choir (1140–1144)
Suger's western extension was completed in 1140 and the three new chapels in the narthex were consecrated on 9 June of that year, but the Romanesque nave between was yet unchanged. He wrote about the new narthex at the west end and proposed chapels at the east: "Once the new rear part is joined to the part in front, the church shines with its middle part brightened. For bright is that which is brightly coupled with the bright, and bright is the noble edifice which is pervaded by the new light."
Suger's great innovation in the new choir was the replacement of the heavy dividing walls in the apse and ambulatory with slender columns, so that the interior of that part of the church was filled with light. He described "A circular string of chapels, by virtue of which the whole church would shine with the wonderful and uninterrupted light of most luminous windows, pervading the interior beauty."
One of these chapels was dedicated to Saint Osmanna, and held her relics.
Suger's masons drew on elements which evolved or had been introduced to Romanesque architecture: the rib vault with pointed arches, and exterior buttresses which made it possible to have larger windows and to eliminate interior walls. It was the first time that these features had all been drawn together; and the new style evolved radically from the previous Romanesque architecture by the lightness of the structure and the unusually large size of the stained glass windows.
The new architecture was full of symbolism. The twelve columns in the choir represented the twelve Apostles, and the light represented the Holy Spirit.
Like many French clerics in the 12th century AD, he was a follower of Pseudo-Dionysius the Areopagite, a 6th-century mystic who equated the slightest reflection or glint with divine light. Suger's own words were carved in the nave: "For bright is that which is brightly coupled with the bright/and bright is the noble edifice which is pervaded by the new light." Following Suger's example, large stained glass windows filling the interior with mystical light became a prominent feature of Gothic architecture.
Two different architects, or master masons, were involved in the 12th century rebuilding. Both remain anonymous but their work can be distinguished on stylistic grounds. The first, who was responsible for the initial work at the western end, favoured conventional Romanesque capitals and moulding profiles with rich and individualised detailing. His successor, who completed the western facade and upper storeys of the narthex, before going on to build the new choir, displayed a more restrained approach to decorative effects, relying on a simple repertoire of motifs, which may have proved more suitable for the lighter Gothic style that he helped to create.
The Portal of Valois was the last of the Gothic structures planned by Suger. It was designed for the original building, but was not yet begun when Suger died in 1151. In the 13th century it was moved to the end of the new transept on the north side of the church. The sculpture of the portal includes six standing figures in the embracements and thirty figures in the voussures, or arches, over the doorway, which probably represent the kings of the Old Testament. The scene in the Tympanum over the doorway depicts the martyrdom of Saint Denis. In their realism and finesse, they were a landmark in Gothic sculpture.
The new structure was finished and dedicated on 11 June 1144, in the presence of the king. The Abbey of St Denis thus became the prototype for further building in the royal domain of northern France. Through the rule of the Angevin dynasty, the style was introduced to England and spread throughout France, the Low Countries, Germany, Spain, northern Italy and Sicily.
Reconstruction of the Nave (13th century)
Suger died in 1151 with the Gothic reconstruction incomplete. In 1231, Abbot Odo Clement began work on the rebuilding of the Carolingian nave, which remained sandwiched incongruously between Suger's Gothic works to the east and west. Both the nave and the upper parts of Suger's choir were replaced in the Rayonnant Gothic style. From the start it appears that Abbot Odo, with the approval of the regent Blanche of Castile and her son, the young King Louis IX, planned for the new nave and its large crossing to have a much clearer focus as the French 'royal necropolis', or burial place. That plan was fulfilled in 1264 under Abbot Matthew of Vendôme when the bones of 16 former kings and queens were relocated to new tombs arranged around the crossing, eight Carolingian monarchs to the south and eight Capetians to the north. These tombs, featuring lifelike carved recumbent effigies or gisants lying on raised bases, were badly damaged during the French revolution though all but two were subsequently restored by Viollet le Duc in 1860.
