Église de l'Immaculée-Conception, Gothic Revival church in 12th arrondissement, France.

The Église de l'Immaculée-Conception is a church built in the Gothic Revival style with pointed arches and ornamental stonework that define its exterior and interior. The building features ribbed vaults and decorative elements typical of this architectural tradition.

The parish was created in July 1874 for the growing Picpus and Bel-Air districts, first under the patronage of Saint Radegonde. Mademoiselle Roland-Gosselin bought the land for 40,000 francs and paid 143,000 francs for the building, designed by Édouard Delebarre de Bay. Construction began on 19 March 1875 and lasted six months; Cardinal Guibert inaugurated the church on 29 September 1875.

The choir paintings are by Victor Zier, a Polish-born painter active in France in the late 19th century. The altar, baptismal font and cross were made by sculptor Dominique Kaeppelin and installed around 1979-1980, after the Second Vatican Council, when he reworked the choir. The four bells in the tower sound E-flat, F, G and A-flat.

The church is located in the 12th arrondissement and is easily accessible by metro at Nation and Picpus stations nearby. Several bus routes serve the area, making it simple to reach from different parts of the city.

The church organ was originally built in 1881 and later underwent major modifications that changed its sound and capabilities. These alterations transformed the instrument into something quite different from its original form.
