Basilica of Saint-Denis

The site began as a Gallo-Roman cemetery. Denis, by tradition the first bishop of Paris, was beheaded on Montmartre in about 250; a martyrium went up over his grave around 313 and was enlarged into a basilica under Saint Genevieve, who bought land here in about 475. Dagobert I turned the church into the Benedictine Abbey of Saint Denis in 632, and had his councillor Eligius, a goldsmith by training, make a new shrine for the saint's remains.

Pepin the Short vowed at his second coronation at Saint-Denis, in 754, to rebuild the old abbey; the new church was consecrated in 775, Charlemagne present. A crypt beneath the apse let pilgrims circle the sarcophagus of Denis; it could not hold the growing numbers, and in about 832 Abbot Hilduin built a second crypt.

Suger became abbot in 1122 and was minister to Louis VI and Louis VII. By his own account he rebuilt because the old church was decrepit and could not cope with the pilgrim crowds. From about 1135 he demolished the Carolingian façade, extended the nave four bays westward and added a narthex whose buttresses and string-courses marked out the divisions of the front, a break with Romanesque practice. Its chapels were consecrated on 9 June 1140.

In the choir that followed he replaced the heavy dividing walls of apse and ambulatory with slender columns, filling the east end with light. Rib vaults with pointed arches and exterior buttresses had each appeared in Romanesque building, but here they were drawn together for the first time. The choir was dedicated on 11 June 1144 in the king's presence, and its completion is widely considered the first use of every element of Gothic architecture. Suger died in 1151 with the work unfinished.

In 1231 Abbot Odo Clement began replacing the Carolingian nave still sandwiched between Suger's works, and the upper choir with it, in the Rayonnant style, with wall area cut to a minimum and two rose windows twelve metres across in the enlarged transepts. The architect is unknown; the attribution to Pierre de Montreuil rests on an unrelated 1247 document calling him a mason from Saint-Denis.

Odo, with the approval of the regent Blanche of Castile and the young Louis IX, seems to have planned the new nave and crossing as the royal burial place. In 1264, under Abbot Matthew of Vendôme, the bones of sixteen kings and queens were moved to new tombs around the crossing, eight Carolingians to the south and eight Capetians to the north. All but five kings of France were buried here: Charlemagne, Philip I, Louis XI, Charles X and Louis Philippe I lie elsewhere. The abbey kept the coronation regalia, and from 1124 kings leaving for war carried off the oriflamme of St Denis, a flag retired in 1488.

The monks sang their last services on 14 September 1792 and the monastery was dissolved the next day; the church was used to store grain and flour. In 1793 the National Convention ordered the royal tombs destroyed. The older monarchs were taken from their coffins that August for the revolutionary Festival of Reunion, the Valois and Bourbons in October to celebrate the execution of Marie Antoinette, and the bodies were thrown into three trenches and covered with lime. Alexandre Lenoir saved many monuments by claiming them for his Museum of French Monuments. In 1794 the roof lead was stripped to be melted into bullets.

Napoleon reconsecrated the church in 1806 and meant it for his own tomb, but left the royal remains in their mass graves. When the restored Bourbons had the graves opened in 1817, only portions of three bodies were intact; the bones of 158 were gathered into an ossuary behind marble plates bearing their names. Louis XVIII, entombed in 1824, was the last king buried here.

François Debret, chief architect from 1813, spent thirty years repairing revolutionary damage. After lightning destroyed the spire he put up a replacement quickly; hurricanes in 1842 and 1843 and a tornado in 1845 damaged it, and he was ordered to dismantle it. He resigned, and Eugène Viollet-le-Duc replaced much of his work and rearranged the tombs, working on until his death in 1879. The church was classified a historical monument in 1862.

It lost cathedral rank in 1895 when Napoleon's chapter was dissolved, and regained it in 1966 with the new diocese of Saint-Denis. The building is run by the Centre des monuments nationaux and has been on France's tentative World Heritage list since 1996. Work to rebuild the spire was inaugurated on 14 March 2025 and is expected to run five years.
