Église Notre-Dame-de-Toutes-Joies, Catholic church in central Nantes, France

église Notre-Dame-de-Toutes-Joies is a church building in Nantes composed of two structurally distinct sections built in different periods. A stone choir from the 1800s connects with a concrete nave constructed later, creating an unusual architectural contrast between old and new materials.

The building was constructed across two separate periods spanning more than a century. What began as a stone structure in the 1800s was later expanded with a modern concrete addition in the following century.

The parish now bearing the name Saint-Jean-Paul-II was formed by merging the former parishes of Sainte-Thérèse-de-l'Enfant-Jésus and Notre-Dame-de-Toutes-Joies. The name "Toutes-Joies" (All Joys) is the church's own dedication, and the building stands within the Hauts-Pavés - Saint-Félix district, framed by the streets Octave-Feuillet, Germain-Boffrand, Alexandre-Dumas and Chanoine-Courtonne.

The building hosts regular worship services and religious events throughout the year for those wishing to attend. It sits in a central Nantes location and is easily accessible on foot from the surrounding neighborhoods.

The church's organ, built by Louis Debierre in 1863, is listed as a monument historique. Debierre, based in Nantes, also built the organ of the city's basilica of Saint-Nicolas. The instrument is one of the elements that led to the building being noticed beyond its parish.
