The Saint-Denis Art and History museum is a particularly original place to visit. Notable residents at the building have included, between 1770 and 1787, Louise of France, the youngest daughter of Louis XV, who had the chapel built. In addition to the place's charm, its specificity also has to do with the diversity of its collections. There are rooms dedicated to the history of the convent and the daily life of the sisters, to the history of the Hôtel-Dieu, and to medieval architecture. The apothecary is considered as one of the most interesting in France, and the permanent exhibition related to the siege of the Paris Commune in 1870-1871 is sure to interest visitors.

The Saint-Denis Museum of Art and History also has a very rich collection related to Paul Éluard, the city's native poet, as well as an interesting collection of prints and caricatures. Outside, visitors can also enjoy the Garden of the Five Senses between March and October. In addition to visiting exhibitions, there are also conferences and family workshops organised by the museum.
