Here's the opening paragraph of an article from Ouest-France, also posted at François Desouche. Unfortunately, the rest of the article is accessible only through subscription.
The awakening to religion is accompanied by an intimate knowledge of places of worship. Eighth-graders from the Saint-Pierre aux Essarts middle school, open-minded and curious, came to look at the mosque. An in-depth exchange with Ali Bensaada, the prison chaplain, followed. Thanks to this visit, the children will have an image of the place where Islam is lived. A good way to best understand their courses dealing with the beginnings of Islam.
The mosque in question is located in La Roche sur Yon, department of the Vendée, a department that has remained more traditional than the rest of France. But apparently not traditional enough.
