The Madeleine and the Grands Boulevards
8e and 9e arrondissements · nine churches · 22 recorded visits

On the Right Bank, the eighth arrondissement reaches west from the Madeleine past the avenue George-V and the avenue Hoche, and the ninth rises north from the Grands Boulevards. Nine churches in the record stand in these two arrondissements.
Most were built or completed in the nineteenth century, and they show its range. La Madeleine, begun under Louis XV and completed in 1842, takes the form of a Roman temple. Notre-Dame-de-Lorette follows the Roman basilicas; Saint-Augustin and Saint-Eugène-Sainte-Cécile rest on iron; Sainte-Trinité looks to the Italian Renaissance; the American Cathedral is Gothic Revival. Saint-Louis-d’Antin began as the chapel of a Capuchin convent of 1782, and the Lutheran church of the Rédemption occupies a former unloading hall of the 1820s.
Sainte-Trinité has five recorded visits, from March 2019 to February 2026, and a photograph from each; Saint-Augustin and La Madeleine have four each.
