Come (re)discover this discreet and sober church of the seventeenth century... which nevertheless houses rich works of art, collected and offered throughout the nineteenth century. Behind the scaffolding and tarpaulins that conceal the work of the restorers and reduce the large organs to silence**, let yourself** tell the story of the building of a church, closely linked to the development of Île Saint-Louis; its innovative architecture, characteristic of the Catholic Counter-Reformation; its epic safeguard during the revolutionary period; its abundant ornamentation, due to the generosity of an exceptional parish priest; some of its many stained glass windows, paintings and sculptures. Let yourself be introduced to Saint Geneviève, patron saint of the diocese, and Saint Louis, patron saint of the parish. Leaflets in French and English are also at your disposal to guide you through the church, to present the ongoing restoration campaign.
