Basilica Cathedral of Saint-Denis

Basilica Cathedral of Saint-Denis is in Saint-Denis, Île-de-France, France and is a foundational monument of Gothic architecture, built over the traditional tomb of St. Denis and serving for centuries as the burial church of French royalty.. A first church was probably built in the 5th century over the tomb associated with St. Denis.

From the burial of King Dagobert in 639, Saint-Denis developed into the principal royal necropolis. Major 12th-century works under Abbot Suger helped establish a new Gothic architectural language, followed by further 13th-century rebuilding. The former abbey church became the cathedral of the Diocese of Saint-Denis in 1966.

Architecturally, the site is principally Gothic. Its documented heritage status is Major Gothic monument and royal necropolis. The site is centered on the tomb traditionally identified with St. Denis, patron saint of France, and remains a place of Christian veneration.

Saint-Denis also preserves an exceptional concentration of royal funerary monuments. The official monument history records the burials of forty kings and twenty-six queens over many centuries, making the church both a functioning cathedral and one of the principal places for understanding the religious dimension of the French monarchy.
