It is the burial site of almost every French king from the 7th century to the late 18th century.
The heart of King Louis XVII is encased within a crystal urn inside the basilica.
Abbot Suger's reconstruction in the 1140s is widely considered the birth of Gothic architecture.
The basilica features an early 12th-century 'chevet' which introduced the revolutionary ambulatory with radiating chapels.
During the French Revolution, the royal tombs were desecrated and the remains were exhumed and cast into mass graves.
The cathedral serves as an active parish church as well as a historical monument managed by the Centre des Monuments Nationaux.
The crypt contains a Merovingian-era sarcophagus dating back to the late Roman period.
The Basilique Cathédrale Saint-Denis is recognized as the first major structure built in the Gothic architectural style, initiated by Abbot Suger in the 12th century. It serves as the primary necropolis of French royalty, housing the remains of 43 kings, 32 queens, and 63 princes and princesses. The site rests on the burial place of Saint Denis, the patron saint of France, who was martyred in the 3rd century. The interior contains over 70 sculpted tomb monuments, representing the largest collection of medieval funerary art in Europe. The western facade features the first rose window in a Gothic cathedral, which became a blueprint for later French religious architecture. Its structural innovations, including the use of pointed arches and rib vaults, allowed for unprecedented height and light penetration through stained glass. The building was elevated to cathedral status in 1966. Its architecture underwent a significant restoration by Eugène Viollet-le-Duc in the 19th century.
The central nave looking toward the high altar captures the verticality and light of the early Gothic design.
