Sainte-Jeanne-de-Chantal, Byzantine Revival church in 16th arrondissement, France.

Sainte-Jeanne-de-Chantal is a church in the 16th arrondissement featuring curved arches, rounded domes, and decorative mosaics in Byzantine style. The building demonstrates how traditional Eastern architectural forms were adapted into a modern French structure.

The first stone was laid in 1932; the architect was Julien Barbier, and a local woman who entered the Visitation convent helped fund the work. Bombed by the Allies during the Second World War because of the nearby Renault factories, the church was rebuilt under the Chantiers du Cardinal, with Charles Nicod enlarging the nave and flattening the dome. Work continued until 1962.

The separate bell tower holds four swinging bells; the three cast in 2004 by the Cornille-Havard foundry in Villedieu-les-Poêles were painted in colour by artist Marc-Antoine Orellana, a technique rarely used in France. Each bell carries an inscription: Esther quotes the Book of Esther, Françoise a line of Saint Francis de Sales, Jeanne a saying of Jeanne de Chantal.

The church faces the place de la Porte-de-Saint-Cloud, at the Porte de Saint-Cloud in the 16th arrondissement, and the separate bell tower marks the square. The nave was enlarged and the dome flattened in the post-war redesign, so the interior reads as one broad volume; the Chapel of the Blessed Sacrament in the apse can be closed off from the nave by a large curtain. Only that chapel has figurative stained glass, the eight windows of 1954 by Jacques Le Chevallier illustrating the Litany of the Virgin.

This is one of very few Byzantine style churches built in Paris during the twentieth century's modernization wave. The uncommon architectural choice made it stand apart from typical post-war construction projects in the city.
