Église Saint-Christophe-de-Javel

The church of Notre-Dame-d'Auteuil replaces a first church from the 10th century, rebuilt in the 14th century, then enlarged in the 15th and 17th centuries. Having become too small for the growing population, the church was rebuilt between 1877 and 1892, as Auteuil, originally a hamlet with its own parish, was attached to Paris in 1860. The church was built in the Romanesque-Byzantine style by the workshop of the diocesan architect Joseph Auguste Émile Vaudremer.

The church of St. Leon is a parish church built in the 1920s and 1930s. The church was designed by Emile Brunet. It is built of concrete covered with bricks. The art deco-inspired decoration (stained glass windows, mosaics, sculptures, ironwork) is characteristic of the 1930s and 1940s. The mosaic is the work of Auguste Labouret.

Notre-Dame-de-l'Assomption de Passy was built by the Pères de la Miséricorde, a missionary order for the rechristianisation of cities, at the end of the 19th century. Following the law of 1901, the Fathers were expelled and the church was closed until 1907 when it was reopened as an annexe chapel of the church of Notre-Dame-de-Grâce-de-Passy. In 1914, the church became a parish church and in 1928, the church took the name of Notre-Dame-de-l'Assomption.
