    South of the Bois de Boulogne, the Seine loops around Boulogne-Billancourt, with Saint-Cloud on the far bank; to the east, Issy-les-Moulineaux and Montrouge border the southern arrondissements of Paris. Five of their churches are in the record.

    Notre-Dame-de-Boulogne was begun in the fourteenth century and Saint-Étienne at Issy in the seventeenth. Saint-Clodoald at Saint-Cloud was rebuilt under the Second Empire, and Saint-Jacques-le-Majeur at Montrouge was raised in reinforced concrete in the 1930s. Sainte-Cécile, in the north of Boulogne, is served by the Brothers of Saint John.

    Saint-Jacques-le-Majeur has three recorded visits, two in June 2024 and one in March 2026; each of the others has one.
