Saint-Denis, France, an industrial suburb of Paris in the Seine department. It lies to the north of Paris on the Seine River. Chemicals, metals, railway equipment, tractors, automobiles, compressors, soap, glass, and many other products are manufactured.

Saint-Denis is best known for the magnificent abbey church of St. Denis, burial place of the kings of France. Within the church are the royal tombs, bearing sculptured likenesses (many of them the only portraits, or the most authentic ones) of most of the French monarchs and their families. The church is one of the first masterpieces of Gothic architecture.

The town of Saint-Denis grew up at the place where Denis, who became France's patron saint, is said to have been martyred. .) His shrine attracted many pilgrims. In the seventh century an abbey was established here. The abbey church was built in the 12th century and was designated as the royal mausoleum by Louis IX in the 13th century.

During the French Revolution, some of the tombs were destroyed by order of the revolutionary government. The royal remains were removed and thrown into a common grave. The town was temporarily renamed Franciade and the church turned into a temple of reason. In the 19th century the church and those tombs that had not been destroyed were restored.
