Armenian Cathedral of St. John the Baptist

Neo-Gothic building built from 1881 to 1884 in a style that reflects the codes of 13th century English architecture, by the architect George-Edmund Street. The bell tower was consecrated in 1923 as a tribute to the Americans who died in the First World War. In the building there are fifty-one flags of the United States of America hanging in the nave.

Saint Stephen's Greek Cathedral is the cathedral of the Greek Orthodox Church of Paris and the seat of the Greek Orthodox metropolis of France. It was built under the direction of the architect Emile Vaudremer. The interior walls of the church were decorated by Charles Lameire and the marble iconostasis by Ludwig Thiersch. Vaudremer commissioned Léon Avenet to create the stained glass windows. On 9 October 1962, the marriage of Édith Piaf and Théo Sarapo was celebrated in the cathedral and on 20 September 1977, the funeral of Maria Callas took place in the cathedral.

Saint-Pierre-de-Chaillot was built in the 1930s, in two stages, and completed in 1938. It was designed by the architect Emile Bois, then chief architect of the city of Paris. This new church replaces a previous church. The former church opened onto Rue de Chaillot, with only a brick-fronted chapel opening onto Avenue Marceau. Nothing remains of this old church except a statue of the Virgin, the Virgin of Chaillot.
