When the Louvre was a royal place, Saint Germain l’Auxerrois was the king’s church. It accordingly drew an assortment of royalty, courtesans, men of art and law, and local artisans. Its architecture is in the Gothic style. Inside the church, you can admire great stained glass windows, the beautiful organ and a few other work of art. The bell, put up in 1529, was used to signal the beginning of the massacre of the Saint-Barthélémy in 1572. (Watch the film “La reine Margot”, with Isabelle Adjani.) During the Revolution, it became a police station, a town hall, a barn and a printing house!… Viollet-le-Duc restaured the building during the XIXth century. Free entry but no visit during the service ( mass).
