Église Saint-Eustache is the great parish church of Les Halles, built in a mix of late Gothic scale and Renaissance detail. Its high interior holds stained glass, paintings, and one of France's largest church organs.
The church is easy to visit while crossing central Paris between the Louvre, Les Halles, and the Centre Pompidou. Outside, the oversized head sculpture Écoute has become a familiar photo stop beside the south facade.
